Normal Mode / Economy Mode
The CL-A12/16 clocks have two different modes in which they will operate. Normal mode allows the clock to
transmit/receive every 4 hours. This mode will allow the clock to have a 5 year battery life (provided good reception).
Economical mode allows the clock to transmit/receive every 12 hours. This mode will allow the clock to have up to a 8
year battery life (provided good reception).
Normal mode is defaulted when shipped from the factory.
To toggle this mode, push and release the Diagnostic Switch and the Transmit/Receive switch simultaneously. If 5 year
mode is selected, the LED will be solid RED for two minutes and the second hand will go to 5 (25 seconds). If 8 year
mode is selected, the LED will be solid GREEN for two minutes and the second hand will go to 8 (40 seconds).
IMPORTANT: If a clock is being added to an existing system, it must be in normal mode.

1. Frequently Asked Questions
What battery size do I use for the wireless clock?
The batteries required are two (2) "D" cell batteries. The recommended battery type is "Duracell: Procell [D] size".
Will the clock cause interference with any of my other wireless devices?
No, the CL Series wireless clock works on 915 - 928 MHz frequency-hopping technology. The clock switches frequencies
automatically when the receiver and transceiver is open, thus interference is avoided.
How long does it take for the clock to receive a signal?
Upon power up of the clock, the receiver will be turned on for ten (10) minutes until the signal is acquired. If the user wishes to
manually look for the signal, press the Transmit/Receive switch twice on the movement.
Can the clocks be set manually to display the correct time at installation (as a temporary measure until the master clock
is installed)?
CL Series clocks can NOT be set manually.
2. Troubleshooting
What happens if I power up the clock and the clock is not moving?
The clock should move at normal speed upon power up. If it does not move at normal speed, check the battery and make sure
the clock receives power. Also, be sure to remove the pin prior to starting up the clock.
What happens if the clock does not receive the signal?
Take the clock within close proximity to the CL-RFT Transmitter and power up the clock. If the clock is battery operated, remove
the battery and put the battery back in again or press the Transmit/Receive button twice. If the clock does not correct, call Viking
technical support.
What happens if the clock shows the wrong time?
Move the clock to Diagnostic #1 in order to find the last time that it received the signal. Perform a Diagnostic #3 to check the
gears for the clock.
How do you know if the clock receives a good signal?
Perform Diagnostic #2. See page 7 for detailed instructions.
I have a location with a marginal signal. What should I do?
Move your Transmitter closer to the location or add a Repeater (CL-RFT with JP1 and JP2 in "Repeater" position, see page 3)
between the Transmitter and the location with marginal signal.
3. Diagnostic Testing
The number of times that the switch is pressed will determine the diagnostic mode. After determining the diagnostic mode, the
LED between the two (2) switches will start flashing a green light. The number of flashes will display the diagnostic number.
Diagnostic #1
This diagnostic will determine how long (# of hours) since the clock last received the communication signal. To enter diagnostic
#1 mode, push the Diagnostic Switch once which is indicated by the green LED flashing one time with a 2 second break.
A. While in diagnostic modes, hour and minute hands continue to run normally.
B. The second hand will display how long since the clock received time signal (please see table on Page 7 for details).
C. After three (3) minutes, the clock will resume normal operation.
