Battery Installation or Replacement 
To Install Battery 
1. Align the tabs on the top of the bat-
tery to the guide rails on the radio 
(Figure 2).
2. Press battery and radio together.
3. Slide the battery towards the top of 
the radio until the battery latches 
click into place (arrow 1). 
To Remove Battery 
The basic operation needed for bat-
tery removal is illustrated in 
Figure 2.
1. Disengage both battery latches, 
located on each side of the bottom 
of the radio (arrow 1).
2. Move battery down on guide rails 
about 1/2 inch (arrow 2).
3. Pull the battery away from the 
guide rails and remove from 
housing.
On page 12 there are two different 
methods for battery removal.
NOTE 
Before each removal attempt, push battery bot-
tom towards top of radio to properly seat bat-
tery. Figures 3 & 4 show right-handed 
operators, use mirror image of figures for left-
 
handed users.

Operation P110 16-Channel Portable Radios
 
Operation 
To Power-Up 
Rotate the volume control 1/2 turn clock-
wise to turn on the radio. A power-up 
alert tone is generated for approximately 
1/8 second to indicate that the radio has 
passed a self-test of the microcomputer.
NOTE 
If the short power-up alert tone is not gener-
ated, or if a second low alert tone is generated 
(indicating corrupted radio programming), turn 
the radio off, check the battery (charge or 
replace if necessary), and turn the radio back 
on again. If the power-up alert tone is still not 
generated, a fault exists in the radio. Contact 
 
your local Motorola Radius dealer. 
To Receive 
1. Set the channel selector to the 
desired channel position.
2. Listen for a transmission and adjust the volume control 
to a comfortable listening level. If no transmission is 
heard, depress and hold the volume control button to 
unsquelch the radio and adjust the volume to a com-
fortable listening level.
3. The radio is now set to receive all calls on the selected 
frequency.
4. If you wish to monitor a channel (disable PL/DPL) press 
the side mounted control button. If programmed as a 
Monitor Button, the LED glows yellow for 4 seconds to 
confirm that the coded squelch is disabled. Any time 
the PTT button is pressed when the P110 radio is in the 
monitor mode (disable PL/DPL), the LED temporarily 
glows yellow to remind you that this state is active. The 
radio remains in the monitor mode until the control but-
ton is pressed again, to reverse the state.

P110 16-Channel Portable Radios Operation
 
5. If programmed as a Volume Set Button (manual moni-
tor), the radio has the ability to monitor until the button 
is released. While pressed, a “rushing noise” will be 
present which indicates the current level setting of the 
volume control.
NOTE 
All P110 radio models have an internal squelch 
setting which is adjusted at the factory. The 
squelch level setting is not a user-operated con-
trol; however, it may be reprogrammed using 
the Radio Service Software available at your 
 
local Motorola Radius dealer. 
To Transmit 
1. Set the channel selector to the desired channel position.
2. Do not interrupt another user. Listen for activity on your 
channel. If the channel on which you are transmitting is 
programmed to receive PL/DPL, momentarily depress 
the control button to listen for channel activity. The 
channel must be clear before transmitting.
3. While holding the radio in a vertical position with the 
speaker-microphone grille two to three inches from 
your mouth, press the PTT button on the side of the 
radio and speak slowly and clearly into the grille area. 
When finished transmitting, release the PTT button to 
receive. When the PTT button is depressed, the LED 
glows red and remains on for the entire length of the 
transmission, and turns off when the PTT button is 
released.
NOTE 
When the PTT button is depressed (and as long 
as the PTT button remains depressed), The 
battery voltage is automatically monitored and if 
the voltage is low, the LED flashes red to alert 
you of the low battery condition. In addition, a 
double alert tone is sounded when the PTT but-
 
ton is released.

Operation with Standard Features P110 16-Channel Portable Radios
 
Operation with Standard Features 
To fit your particular needs, a number of features are available 
to enhance the operation of your P110 radio. These capability 
features are described for you in this section. 
Time-Out Timer 
The Time-Out Timer (T.O.T) feature alerts you if the trans-
mitter is keyed for a long period. This feature prevents chan-
nel tie-up and excess battery drain in case of an inadvertent 
keying of the transmitter. The radio operates normally in the 
receive mode with the T.O.T. feature. However, in the trans-
mit mode, a single transmission (uninterrupted depression 
of the PTT button) “times-out” after 30 or 60 seconds and 
the radio reverts back to the receive mode, even with the 
PTT button remaining depressed. After the 30 or 60 second 
time out, a continuous alert tone is generated in the receive 
mode until the PTT button is released. 
Volume Set 
When programmed as a Vol-
ume Set button, the Control 
button will initiate the volume 
set feature. This gives the 
radio the ability to monitor the 
current radio volume level 
whenever this button is 
pressed. A “rushing noise” is 
present for the duration of the 
button press that indicates the 
current level setting of the vol-
ume control.

P110 16-Channel Portable Radios Operation with Standard Features
 
Busy Channel Lockout 
Busy Channel Lockout is a privacy feature that prevents the 
radio from listening to or transmitting over conversations 
outside its talkgroup, keeping lines of communication clear. 
Whenever the radio is not allowed to talk, you will hear busy 
tone if you attempt to transmit. The radio will be allowed to 
transmit:
1. when the channel is clear
2. during the groups repeater hang time, until a carrier 
drop is seen
3. when receiving transmissions from your own group 
(Common PL/DPL code).
Whenever a channel is programmed for PL/DPL busy chan-
nel lockout, pressing the Control button does not put the 
radio into the carrier squelch mode. This means that the 
radios with PL/DPL busy channel lockout programmed can-
not monitor or listen to the other groups transmissions. Fur-
thermore, the volume set function is also disabled on any 
channel that is preprogrammed as a PL/DPL busy channel 
lockout channel.
On carrier squelch channels, Transmit Inhibit is available to 
prohibit transmissions when any carrier is present.

Operation with Standard Features P110 16-Channel Portable Radios
 
Voice Activated Transmission (VOX) 
When hands-free operation is desired, the P110 radio can 
be activated by voice alone using the VOX feature. The 
radio has circuitry and software internal to the radio that 
senses when you speak through an accessory headset and 
will automatically transmit. You will know you are transmit-
ting when you hear yourself in the headset speaker. Opera-
tion is totally automatic; no external controls are required. 
To Activate the VOX Feature 
1. Turn the radio off.
2. Insert a headset, without a PTT button, in the acces-
sory connector on a channel programmed for VOX 
operation.
3. Turn the radio on. The VOX feature will be ready to 
function. You can operate the radio manually, at any 
time, by pressing the PTT button.
4. Restart the VOX feature by turning the radio off/on or 
changing the channel.
NOTE 
An external headset accessory must be attached 
to the P110 radio to activate VOX operation. The 
radio operates normally, using the PTT button, 
 
whenever the headset is not attached.

P110 16-Channel Portable Radios DTMF Telephone Interconnect
 
DTMF Telephone  Interconnect 
You can encode Dual Tone Multiple Frequency (DTMF) 
tones through the optional 12 button keypad. The tones are 
used for:
• access to the landline telephone network
• remote control operation 
DTMF Telephone  Interconnect
Operation 
1. Press and hold the PTT button.
2. Press the desired numeric keys on 
the DTMF keypad to transmit the 
tones. As long as the PTT button is 
held while the digits are pressed, 
the corresponding DTMF tones 
are transmitted. 
NOTE 
After this operation is completed, the PTT but-
 
ton resumes its normal function.
