SECTION TWO
OPERATION
2.0 GENERAL
The ATS Model 1225 Hand Held Transceiver is one of the System 1200 devices. The System
1200 devices were designed to provide secure communications to law enforcement agencies. This section describes
the operation of the Model 1225 with the other units in the System 1200 family.
2.1 ATS 1200 SYSTEM COMPONENTS
The ATS System 1200 components include the Model 1245 monitor Station and the Series 1250
Transmitters.
2.2 MODEL 1225 OPERATION
Before operating the Model 1225, the user should read Section 1.2 of this manual, where the user
controls and interfaces are described.
The ATS System 1200 was designed to support two primary operating scenarios. The first
scenario is direct transceiver-to-transceiver communications. In this scenario, communications occur between
individual transceivers, using either Channel A or Channel B. The second scenario requires the use of a repeater to
extend the operating range. In the Repeater Mode, system components transmit on Channel A (or Channel C) and
receive on Channel B. The Model 1240 Portable Repeater was designed primarily to support the second scenario
but it also provides for direct communications capability.
To communicate with other units in the direct transceiver-to-transceiver mode, all units must be
set to the same channel, either Channel A or B, set to the same code, either C or P and have the same keys loaded.
In the repeater (R) mode, the Model 1240 Portable Repeater receives transmissions on Channel A and re-transmits
them on Channel B. To use the repeater, the Model 1225 CHAN select must be set to R.
A fully charged battery pack should be installed onto the Model 1225 Hand Held Transceiver prior
to each deployment. To operate the Model 1225, place the CHAN switch to the desired position, A, B, or R
(repeater), select either the common (C) or private (P) code with the CODE switch and turn the unit on by rotating
the VOLUME control from the OFF position.
