BATTERY REPLACEMENT
Battery  replacement  is  simple  with  the  ID  Excel  drop-in  battery 
compartments:  just  pop  the  doors  open.  Two  9-volt  transistor 
batteries are located in separate compartments at the rear of the 
housing. When it’s time to replace the batteries, always replace 
both of them. 
1. To open the battery compartments, press gently 
down and out on the battery door latch. The doors 
are tethered; do not attempt to completely remove 
them. 
2. Tilt the housing gently and the batteries will slide 
out. 
3. Insert the new batteries. Make sure the contact 
end  goes  in  first  and  that  you  match  the  polarity 
markings on the control housing.
