Additional Information
Power
The Pendant RPA unit is powered by a 230mA/H CR2032. The battery can be changed by removing the two holding
screws at the back of the unit. Battery polarity is indicated on the inside of the unit and the holder is designed to prevent
incorrect insertion. On inserting the battery, the transmission indicator will light for a short time to confirm operation.
To replace the battery, remove the two holding screws at the top and bottom of the reverse side of the unit. The
replacement battery fits into the plastic battery casing on the unit PCB, and battery polarity is indicated on the casing itself.
Buttons
There are two buttons (3, 4) which can be pressed in various combinations to cause a transmission, indicated by the
transmission indicator LED on the side of the unit. Transmission continues for as long as the buttons are pressed. These
buttons can be programmed to operate individually or in combinations (this is performed from within the Radio PA Setup
menu in 3GS Programming).
Lanyard
The unit comes fitted with a lanyard necklace (1) which has a stress break designed to comply with relevant European
health and safety standards. The lanyard is attached via a ringclip (2) to a spring loaded pull switch which is triggered when
