Transmitter Setup

 

Battery Selection and Installation 

An alkaline 9-volt battery is recommended. 

Make certain the transmitter power 

switch is Off before installing or changing batteries. 

 
When inserting the battery, 

observe correct polarity as marked inside the battery 

compartment

. The transmitter housings are designed to prevent incorrect 

installation of the battery; 

do not force the battery in

. Reversed batteries may 

cause damage to the transmitter. 

 
UniPak™ Transmitter Battery Installation 

1. Slide off the battery cover as shown in Figure E. 
 
2. Carefully insert a fresh 9V alkaline battery, observing polarity markings. 
 
3. Replace the battery cover (Fig. F). 

 
Handheld Transmitter Battery Installation 

1. While holding the upper part of the transmitter body just below the ball-screen, 
unscrew the lower body cover and slide it downward to expose the battery 
compartment (Fig. G). 

Do not attempt to pull the lower body farther down, or to 

gain access to the electronics. 

 
2. Lift the white “battery keeper” arm until it sticks straight out from the mic body 
(no higher). Then carefully insert a fresh 9V alkaline battery, observing polarity 
markings. 
 
3. Screw the body back together. 

Do not overtighten. 

 
Battery Condition Indicator 

The red battery condition indicator (Fig. I/J) should light strongly with a fresh 
battery. As the battery weakens, the indicator will grow dimmer. When the 
indicator becomes very dim or goes out, there is little life left in the battery. 
Replace it at once for continued operation of the transmitter. 
 
All transmitters feature battery-save switches (Fig. E/G). As supplied, the switch 
is set in the High position for maximum range. Switching to the Low position
