2.0  Operation  

 

2.1 Battery Charging 

 

The transmitter is fully operational while the batteries are being 
charged. Charging can occur whether or not the unit is powered on. 

 

When “batt low” appears in the battery icon, the battery life is nearing 
its end.  The transmitter will shut down soon.  Connect the AC/DC 

adapter (12 V /1.5 A) to the unit’s CHARGE jack.  Plug the adapter into 

a wall outlet.  An internal battery charger will control and terminate 
the charging of the 6 NiMH cells within each unit.  When beginning a 

charge cycle with batteries which have been completely depleted, 

allow about two and a half hours for a full charge to be restored.  A 
top-off charge is recommended immediately before use for maximum 

battery life.  

 

 
A flashing red LED indicates a precharge state. Usually it will flash  

for a few moments and then enter a fast charge state, indicated by a 

solid red LED.  The precharge state may last up to a few hours with 
drained batteries and indefinitely if one or more cells have failed.  All 

cells must be replaced in the latter case.  When the LED turns green, 

the batteries are fully charged and enter trickle charge mode 
indefinitely. Fully charged batteries will give six to eight hours of use.   

Also, the battery icon on the display will be completely darkened.  If 
the AC/DC adapter is left connected to the transmitter, the charger 

will initiate a new charge cycle once the batteries have discharged.  

This will occur continually.  Unless the transmitter is in operation, it is 
not recommended to leave the AC/DC adapter connected for more 

than 24 hours. 

 

Though designed for many recharge cycles, the batteries are user 

replaceable. Replace the batteries every 2-3 years. Use only 
Energizer® NH15 AA NiMH rechargeable batteries, as supplied 

originally. The internal charge circuit will only work with NiMH 

rechargeable batteries. Attempting to charge other AA battery types 
such as Alkaline or Lithium Ion will result in damage to the 

transmitter.   

 

Do not store the transmitter with discharged or failed batteries. 

Discharged NiMH batteries can leak acid causing damage to the 

transmitter.
