Lectrosonics UH200d - Manual (Page 7)

Frequency Agile Plug-on UHF Transmitter
BATTERY REPLACEMENT
The UH200D transmitter is powered by a standard alkaline 9 Volt
battery. It is important that you use ONLY ALKALINE OR
LITHIUM batteries for longest life. Standard zinc-carbon batter­
ies marked “heavy duty” or “long-lasting” are not adequate. They
will provide only about 5 minutes of operation. Similarly, ni-cad
rechargeable batteries only give 1 hour of operation, and will also
run down quite abruptly. Alkaline batteries provide about 4.5
hours of operation while lithium batteries will run the unit for
about 12 hours.
To open the battery compartment, press outward on the cover
door in the direction of the arrow as shown in the drawing. Only
slight, sliding pressure is needed to open and close the battery
door.
Swing the door open and take note of the polarity marked inside
showing the location of the positive (+) and negative (-) terminals.
Insert the battery and close the cover by pressing in and across,
reversing the opening procedure outlined above. Note that the
battery door will NOT close if the battery is inserted incorrectly,
since the terminals will hit a protective polarity barrier.
Don’t force the battery door closed. If it is difficult to close, the
battery is in backwards.
The battery life will be affected by the amount of phantom power
supplied to any microphones that require it. A high drain 48 Volt
microphone can shorten battery life by 40% or more. A light drain
15 Volt microphone will make little or no difference in battery life.
The only way to be sure is to test the transmitter and microphone
combination with a brand new battery; then and only then will you
be sure of the combination's battery life.

CAUTION
Lithium batteries will expand and swell if allowed to go into a deep discharge. Be sure to remove lithium batteries as soon as the
display starts flashing DEAD BATTERY. If lithium batteries are allowed to fully discharge while still inside the battery compartment,
they will be very difficult to remove.
Stuck lithium batteries can be avoided by removing the label wrapping around the battery before use. This will allow the battery to
swell but will still leave enough room in the compartment for the battery to fall out normally.
TROUBLESHOOTING
Before going through the following chart, be sure that you have a good battery in the transmitter. It is important that you follow these
steps in the sequence listed.
SYMPTOM POSSIBLE CAUSE
TRANSMITTER BATTERY LED OFF 1. Battery is inserted backwards.
2. Battery is dead.
NO TRANSMITTER MODULATION LEDs 1. Gain control turned all the way down.
2. Battery is in backwards. Check power LED.
3. Mic capsule is damaged or malfunctioning.
4. Mic cable damaged or mis-wired.
5. Phantom power not enabled for mic that requires it.
