Chapter 2 – Digital Wireless System Transmitters
This chapter is intended to quickly familiarize you with the functions of each of the Digital Wireless System
transmitters.

Getting to Know Your TRX900 ( /AA) Bodypack Transmitter

Both the TRX900 and TRX900AA are identical in operation. The only difference is the type of battery used. The
TRX900 uses a single CR123 battery, whereas the TRX900AA uses two AA batteries (Lithium or NiMH). This
section was written based on firmware version

Connectors, Switches and LEDs

Antenna

The transmitter uses a gold plated SSMA connector. Included is an antenna, cut to the correct length for your
transmitter's specific frequency block. You should periodically check that the connector is still securely tightened.
On/Off Switch – Internal/External Power Switch
The Power switch is intentionally set below the frame of the transmitter to prevent accidentally turning it 'OFF'
during use.
When the Zaxcom Stereo Adapter is connected, the On/Off switch becomes an internal or external power select
switch.
