Introduction

The AirTime ATDDC4 Wireless Digital Display Wall Clock is designed with a 4-inch red LED display that can be viewed from distances over 100 feet. The optional 6 digit version provides 2 additional 2-inch digits. The bright red display shows the hour and minutes or as an option the hour, minutes and seconds; can be configured for a 12 or 24 Hour format; and keep time synchronized to a Lathem ATX series transceiver’s wireless correction signal. The ATDDC4 series Wall Clocks can be mounted directly to a wall, to a single gang outlet box or, with optional mounting kits, as double-faced units from the wall or ceiling.

Clock Operation

When the ATDDC4 series Wall Clock is connected to 120vAC (24vAC optional) power, it displays the firmware version for 3 seconds and then changes to 12:00 AM. A flashing LED in the lower right indicates that it is listening to acquire its initial synchronization signal. When a signal is received the LED will extinguish and the internal clock will be set. Note: It may take up to several minutes for the clock to initially synchronize. After initial reception, the LED will only flash when future sync signals are received. The clock will continuously listen and correct itself as needed.
