D. Installation
Place the main CL-RFT Transmitter in the building with optional repeaters (CL-RFT with JP1 and JP2 in "Repeater" position, see
section C above) as needed to cover the entire premise. Repeaters are synchronized wirelessly to the main transmitter.
1. Place the main transmitter (CL-RFT) in a central location (hallway recommended).
2. Pick the location of the optional repeaters.
3. Place the repeaters in a location where the signal is available from the main transmitter.
4. Repeat the above mentioned steps with the corresponding repeaters. Please note that the corresponding repeaters can receive
a signal from another repeater, and not only from the main transmitter.

1. Frequently Asked Questions
Where is the best location for the Transmitter/Repeater to be mounted?
Usually, the hallway is the best location because it is mostly open space in typical applications.
How far can the Transmitter/Repeater transmit the wireless signal?
The Transceiver can transmit up to 6500 ft in open space.
Can analog wireless clocks be combined with digital wireless clocks?
Absolutely. The analog and digital wireless clocks are designed to work together, whether the clocks are running on battery
(analog wireless clock only), or 24 volts (digital clocks only).
Will the Transmitter/Repeater have interference from cordless or cellular phones?
No, because with Viking's innovative frequency-hopping technology, interference will not occur. The repeater switches frequencies
automatically when the receiver and transmitter is open, thus interference is avoided.
My power source is 220 volts. Can the Transmitter/Repeater be powered on that voltage?
Yes, the Transmitter/Repeater can work on 110 volts/50-60 Hz or 220 volts/50-60 Hz.
2. Troubleshooting
The clocks aren't receiving the signal. What should I do?
Make sure that the Transmitter/Repeater is in a place where the signal can be transmitted in open space.
What should I do if the Transmitter/Repeater is not powering up?
Measure the voltage between pins L1 & L2. The voltmeter should read 90 - 230 VAC between the hot and the neutral.
