ATS has developed two antennas for use with the Series 1250 Transmitters and the Model 1250-04 J Battery
Holder. The Model 1250-02 Antenna was developed for use with Models 1252 and 1253. The antennae are low profile and
incorporate a connector to mate with the transmitter connector. The antenna also contains a captured screw which fastens
into the transmitter. Use of these antennas provides a compact, integral unit. ATS has also developed a patch antenna that
is integral to the Model 1250-45 Extended Service Case. This antenna provides improved performance when compared
to the 1250-01 and 1250-02 antenna’s.
2.4 MICROPHONE
The Series 1250 Transmitters are equipped with a built-in microphone. The microphone is mounted facing a hole
in the flat side of the case. The microphone must be faced away from the body. To use the microphone, a shorting plug must
be installed in the microphone connector on the edge of the transmitter case.
The Series 1250 Transmitters will accept an external microphone. To use an external microphone, the shorting
plug must be removed, thereby disabling the internal microphone, and a compatible microphone connected in its place. The
microphone connector is a Microtech DR-4S-4PC.
2.5 CODE SELECT
Access to the Code Select rotary switch is provided through a hole in the flat side of the Series 1250 Transmitters.
A screwdriver must be used. The Private (P) or Common (C) code can be selected by turning the code select switch to the
appropriate stop.
2.6 EXTERNAL ACCESSORIES
The Model 1250 normally uses its internal microphone. Optionally, the shorting plug may be removed and an
external microphone connected.
Normally, the Model 1250 is powered on following the procedures stated in paragraph 2.2.1. Optionally, the
shorting plug may be removed and an external On/Off Switch connected.
An external microphone and an external On/Off switch may be used by removing the shorting plug and uses a Y-
cable to connect to the microphone and switch. The Model 1250-05 Surveillance Kit contains an external microphone, an
external on/off switch and the Y-cable.
The Private Keys can be changed using the Model 1260 Key Loader and Model 1250-03 Key Load Adapter. This
equipment is only required to change the factory loaded, Private Key. The Common Key cannot be changed by the user.
