[T-1] off: Turns unit off and performs battery test.
[T-2] on: Ohm-meter / Fault Locate / Tone: Turns the unit on and cycles through the 
following commands when pressed repeatedly.
 Ohm-meter:  Measures the continuity of the trace conductor/pipe and its far-end 
ground. It is also used to measure the fault resistance to earth. 
Fault Locate: (2273M units only) In this mode, the transmitter sends two alternating 
locating frequencies (577 Hz and 33 kHz) as well as fault signals 10 and 20 Hz. 
Tone:  In the tone mode, the transmitter generates 577 Hz and 200 kHz signals.
[T-3] on: Trace (frequency): Turns the unit on and places the unit in Trace mode.   Select  Frequency:  Press Trace [T-3] repeatedly to cycle through the transmitter’s 
active frequencies (577 Hz, 8 kHz, 33 kHz, and 200 kHz). The selected frequency 
will be displayed [T-4]. ‘ALL' indicates that the following active frequencies are 
transmitting simultaneously: 577 Hz, 8 kHz, 33 kHz and 200 kHz.
[T-4] Digital Display:    Indicator Flags: These flags coincide with the operational mode of the transmitter. 
(From top left to bottom right) Fault mode [T-2] (2273 units only), Tone mode [T-2], 
Trace mode [T-3], Ohm-meter [T-2], Voltage (at start up the transmitter checks for 
foreign voltage), and the Output Level Flag (no flag = normal output; flag = high 
output; flashing flag = maximum output).
Digital Display: Indicates frequency, relative current, resistance, battery level and 
voltage (if present on target).
[T-5] Output Level: Cycles output level; normal, high and maximum. Normal=No Flag; High=Flag; Maximum=Flashing Flag (indicated in Digital Display 
[T-4])
NOTE: An external 12-volt power source is required to obtain Max Output level (12 
watts for 12-watt transmitters and 5 watts for 5-watt transmitters).

NOTE: 12 Watt Output Level varies by frequency. Output is limited to 10 watts at  
33 kHz and 1 watt at 200 kHz using the direct connection method.
[T-6] Output Jack: Port for direct connect cables or 3M
™ Dyna-coupler.
[T-7]  External Jack: Port to connect cigarette lighter adapter cable, or rechargeable 
battery (2200RB). Input voltage level: 9-18 VDC. (Only on 5-watt and 12-watt 
transmitters.)
G.  Maximum Transmitter Output
An external 12V DC source is required for 12-Watt Output (Max setting) using a 12-watt 
transmitter or 5 watt output (Max setting) using a 5-watt transmitter. Connecting the 
rechargeable battery (2200RB) to the External Jack [T-7] will provide this external 
source, or the cigarette lighter adapter cable (included with 12-watt and 5-watt 
transmitters) can be used to connect the DC power from a vehicle’s battery source to 
the transmitter’s External Jack  [T-7].
Press  Output  Level [T-5] twice for maximum output mode.
The indicator flag will flash when the transmitter is in maximum output mode.
Note: The external DC source does not charge the internal batteries.
!  WARNING
To reduce the risk associated with hazardous voltage:
•  Potential for electric shock exists when handling connection cables while the transmitter is 
ON. Make all connections prior to powering on the unit. Turn transmitter OFF before handling 
connection cables.
•  Voltage greater than 240 volts will damage equipment and could cause personal injury or 
death. Make all connections before turning on the transmitter. Follow standard procedures 
for reducing the voltage.
•  Do not change or modify this product in any way.
H.  Rechargeable Battery
The 3M™ Dynatel™ Sealed Gel-Cell Battery  
2200RB can be used as an auxiliary battery in 
3M
™ Dynatel™ Transmitters 2200 Series. It plugs 
into the External Jack  [T-7] and provides power 
for the transmitter. When the rechargeable battery 
is plugged in, normal output, high output, and 
maximum output are available. When the 
rechargeable battery is connected to the 
transmitter, the alkaline batteries are bypassed. 
The rechargeable battery is a lead acid battery 
rated at 5.4 amp-hours and is equipped with a user replaceable fuse (5A/32V).
Note: The internal batteries must be at least 5.4 volts. Do not remove the alkaline 
batteries from the transmitter when using the rechargeable battery. Rechargeable 
battery, or cigarette lighter adapter cable, is required for Maximum output level. 
Rechargeable battery is shown installed in the well of the transmitter case.
