OWNER’S MANUAL — Please read before using this equipment.

Your Indoor/Outdoor Modular Intercom 
System operates as a two-tone doorbell 
intercom and an indoor intercom. The 
doorbell is simple to install without wiring and 
you can add additional stations.

Your doorbell intercom uses four AA 
batteries (not supplied) for power. For the 
best performance and longest life, we 
recommend RadioShack alkaline batteries.

Use only fresh batteries of the 

required size and recommended type. Do not 
mix old and new batteries, different types of 
batteries (standard, alkaline, or 
rechargeable), or rechargeable batteries of 
different capacities.

1. Use a Phillips screwdriver to loosen the 

screws in the doorbell intercom’s battery 
compartment cover, then lift the cover 
off.

2. Insert four AA batteries into the 

compartment as indicated by the polarity 
symbols (+ and –) marked inside.

3. Replace the cover and tighten the 

screws.

 For convenience, set the channel 

(see “Setting the Channel”) while you 
have the battery cover removed.

 Dispose of old batteries promptly 

and properly. Do not burn or bury them.

 If you do not plan to use the 

doorbell for two weeks or longer, remove the 
batteries. Batteries can leak chemicals that 
can destroy electronic parts.

If the doorbell unit operates under severe 
cold weather, use a lithuim type AA battery.

The doorbell and indoor intercoms have 
three selectable operation channels to 
prevent interference from similar products 
nearby. Select the same channel for both the 
doorbell intercom and the indoor intercom.

On the doorbell intercom, slide 

 inside the 

battery compartment to 

 (

912.4

5MHz), 

 

(

913.45

MHz), or 

 (

914.45

MHz).

On the back of the indoor intercom, set 

 

 to the same channel 

number (

, 

 or 

) you chose for the doorbell 

intercom.

 If the doorbell occasionally sounds 

without anyone pressing 

 on the 

doorbell, change the channel settings.

Use a small flat-blade 
screwdriver to 
carefully pull out the 
jumper 

 switch 

located in the battery 
compartment, then 
insert the jumper 

 

switch into the other 
two pins.
