Table 2-2 lists test equipment required to service these and other two-way radios.
† For those customers that need to test the LTR functioning of their radio instead of the R2600, 
purchase the HP8920 with LTR option. Please see your local Hewlett Packard representative for 
this item.NOTE
While all of these items are available from Motorola, most are standard shop 
equipment items, and any equivalent item capable of the same performance may 
be substituted for the...

Transceiver Performance Testing
3.1 General
These radios meet published specifications through their manufacturing process by utilizing high- 
accuracy, laboratory-quality test equipment. The recommended field service equipment approaches 
the accuracy of the manufacturing equipment with few exceptions. This accuracy must be maintained 
in compliance with the manufacturer’s recommended calibration schedule.
3.2 Setup
Supply voltage is provided using a 13.2Vdc power supply. The equipment...

3.3 RF Test Mode
This test mode is for display radios only. When the radio is operating in its normal environment, the 
radio’s microcontroller controls the RF channel selection, transmitter key-up, and receiver muting. 
However, when the unit is on the bench for testing, alignment, or repair, it is removed from its normal 
environment and cannot receive commands from its system. Therefore, the internal microcontroller 
does not key the transmitter or unmute the...

Transceiver Performance Testing3-3
To enter test mode:
1. Turn the radio on.
2. Within ten seconds after the self test is complete, press button P2, five times in succession.
3. After “CSQ CHXX SP25” appears in the display, the radio is on channel XX*, carrier squelch 
mode, 25 kHz channel spacing.
4. Each additional press of P2 scrolls through to the next channel spacing and a corresponding set 
of tones are sounded.
5. Pressing P1 scrolls through and accesses test environments as shown in Table 3-2.
