The base unit can be disconnected from the transformer for use in another location. The battery will last approximately
four (4) hours when unplugged from the transformer. IMPORTANT: You can turn the base unit OFF to conserve
battery power, however it will not receive a signal when OFF.
7. Add Additional Base Units (optional)
If you have purchased additional base units (F3101MBC) to enhance your system, each additional unit’s
ID Code must be programmed into the keypad so they can communicate.
Step 1: Install the battery and turn the base unit ON.
Step 2: Press and release the “ID SET” button on the keypad.
Step 3: Press the number on the keypad that corresponds to the base unit
you are adding. You will hear a number of beeps corresponding to the
number you pressed. For Example: if you are adding a second base unit to
the system, PRESS “2,” the keypad will beep TWO times.
Step 4: Press the “ID SET” button on the base unit for approximately two
seconds then release. You will hear TWO beeps from the base unit and
TWO beeps from the keypad, which means the ID Code is set.
IMPORTANT: Base units need to be placed at least 10 feet apart to
prevent interference.
8. Test the System
IMPORTANT: The base unit and the keypad cannot be within 30 feet of
each other when operating. If units are closer than 30 feet the signal will be
inconsistent and emit speaker feedback. Also, multiple base units must be
no closer than 10 feet from each other to prevent interference.
Have someone press the CALL button on the keypad at the gate. When
the base unit inside the house rings, press the ANSWER button and talk to
the person at the gate to check the connection and range. Then press the
GRANT PERMISSION button and have the person at the gate press any
key on the keypad to activate the gate.
Troubleshooting
Make sure all connections are secure and correct, batteries installed, and base
unit is ON. If you have multiple base units, they should be at least 10 feet apart
to prevent interference.
In rare cases, other devices operating in the same frequency band may cause
interference with the intercom signal. If the system does not communicate at all,
reassign the base unit/keypad ID code as follows (this will require two people):
1. Open the keypad and locate the “ID SET” button above the batteries. Locate
the “ID SET” button on the bottom of the intercom base unit.
2. Make sure the “antenna-to-antenna” distance between the keypad and the
