The AMR RF Transmitter
20
Communication
The transmitter communicates via receiver/ repeater or
programmer units in two ways:
Meter data is sent via one-way UHF communication to a
receiver.
When the data input wires of the transmitter are connected
to a programmer unit which is connected to the AMR
ToolBox PC, programming commands are received from
the ToolBox and transmissions are sent to the air. See
Appendix C for details.
Connectors
The AMR transmitter has one internal connector for the
data input wires.
Internal Battery
The AMR RF transmitter is powered with an internal
lithium battery. The calculated battery life estimate is 13
years, based on 6 transmissions per day, zero repetitions,
in 70ยบ F temperatures.
The battery can be replaced by performing a solder
operation on the terminal leads by authorized personnel in
lab conditions. See Appendix D below for instructions on
replacing the battery.

C a u t i o n
Once the transmitter has been enabled, it
cannot be disabled, unless the battery and
capacitor are detached. If an enabled AMR
transmitter is to be transported by air, the
transmitter housing must be opened and the
battery terminals and capacitor must be
unsoldered.
