C. OPERATING INSTRUCTIONS

UH-16 Handheld Microphone Transmitter

1. Powering the Transmitter

Slide open the BATTERY COMPARTMENT COVER (12) and remove, exposing the

BATTERY COMPARTMENT (14). Insert 2 fresh AA ALKALINE BATTERIES

(15), observing the correct polarity as marked, and slide the COVER back, closing the

BATTERY COMPARTMENT.

Two fresh alkaline AA Batteries can last up to 12 hours in use, but in order to ensure

optimum performance, it is recommended that you replace the batteries after every 8-10

hours of use.

All controls are at the base of the microphone. Turn on the UH-16 by sliding the

OFF/STANDBY/ON SWITCH (15) to the STANDBY position (transmitter on, audio

muted) or the ON position (transmitter and audio both on). The BATTERY

INDICATOR LED (16) will give a single quick flash, indicating usable battery strength.

In the case of dead or low batteries, the LED will either not go on at all, or will stay on

continuously, indicating that the batteries should be replaced with fresh ones. To preserve

battery life, turn the transmitter off when not in use. The channel number on the

CHANNEL LED DISPLAY (18) will extinguish in 10 seconds. The activity indicator

“ “ or “ “ LED will remain on.

2. Selecting the Operating Frequency

In order for the system to operate properly the same channel (frequency of operation)

must be selected for the UH-16 transmitter as was chosen for the UHF-16 receiver. Press

either the UP or DOWN CHANNEL SELECT BUTTON (17) until the channel number

indicated on the 2-segment CHANNEL LED DISPLAY (18) matches that of the UHF-

16 receiver.

3. Selecting the Tone Squelch™ Mode

Hold both the UP and DOWN BUTTONS (17) at the same time for 1 second. The Tone

Squelch™ will cycle from On to Off. See the CHANNEL DISPLAY AND UP/DOWN

BUTTON OPERATION section below.

4. Locking the Keyboard

To avoid accidental reconfiguration of the Channel setting or Tone Squelch™, the

keyboard can be locked by holding both the UP and DOWN BUTTONS (17) at the same

time for 3 seconds. See the CHANNEL DISPLAY AND UP/DOWN BUTTON

OPERATION section below.
