Frequently Asked Questions
Where is the best location for the Repeater to be mounted?
Usually, the hallway is the best location because it is mostly open space in typical applications.
How far can the Repeater transmit the wireless signal?
The Repeater can transmit up to 2000 meters in open space.
Will the Repeater have interference from cordless or cellular phones?
No, because with Valcom’s innovative frequency-hopping technology, interference will not occur.
The repeater switches frequencies automatically when the receiver and transmitter is open, thus in-
terference is avoided.
How do I know if the Repeater is receiving the wireless signal?
On the small circuit board standing vertical on the larger board, there are two LEDs. When the Re-
peater gets the wireless signal from the Transceiver, the LED to the left will flash one time.
Can analog wireless clocks be combined with digital wireless clocks?
The analog and digital wireless clocks are designed to work together, whether the clocks are running
on battery (analog wireless clock only), 24 volts or 110 volts.
My power source is 220 volts. Can the Repeater be powered on that voltage?
Yes, the Transceiver can work on 110 volts/60 Hz or 220 volts/50 Hz.
How do you make the Repeater a Transmitter?
With the repeater powered down, switch both jumpers from repeater to transmitter. Then connect
the Valcom digital output of any Valcom Master Clock to the Valcom Digital input on the repeater,
4 & 5.

Troubleshooting
The clocks aren’t receiving the signal. What should I do?
Make sure that the Repeater is in a place where the signal can be transmitted in open space.
What should I do if the Repeater is not powering up?
Measure the voltage between pins 1 & 3. The voltmeter should read 85 - 135 VAC between
the hot and the neutral.
