Model: 72MHz Personal Series LCD Clock
The Personal Series LCD Clock comes fully assembled and sets up automatically with a few easy steps.
Learn about the guidelines providing what you need to know before you begin, battery use recommendations, and how to set up a Personal Series Clock.
Verify the Transmitter is operating properly with adequate building coverage. During initialization, the clock receives a signal from the Transmitter.
Transmitters with an internal antenna broadcasts its synchronized time continuously to the system clocks and devices.
Transmitters with an external antenna broadcast for only 27 minutes each hour, from 39 minutes before the hour to 6 minutes after the following hour. If you have a Transmitter with an external antenna, follow these guidelines to efficiently initialize your Personal Series Clocks.
Small quantity of Personal Series Clocks: Initialize the clocks during the window in which the Transmitter is broadcasting.
Large quantity of Personal Series Clocks: power cycle (unplug and plug in) the Transmitter, causing it to broadcast continuously for 8 hours, during which you can initialize the clocks.
Allow sufficient time to allow the setup can be performed without interruption.
While setup can be performed in a convenient central location, such as a maintenance facility, once the clock is located at its final installation location, verify it has adequate signal strength.
Use only high quality Alkaline batteries
Always use fresh, superior-quality batteries, with an expiration date at least five years past the installation date.
Batteries should be the same type and date code.
The use of heavy duty and zinc carbon batteries is not recommended, as they will not last as long as high-quality name-brand alkaline batteries.
Do Not Use Lithium or Rechargeable Cells.
On the back of the clock, remove the cover on the battery holder.
Insert 4 C-cell alkaline batteries into the battery holder. Insert the batteries with the battery ‘+’ end to the ‘+’ end of the battery holder to achieve proper battery orientation.
All elements on the LCD display will light up and the unit will beep once.
After four seconds, dashes appear on the display and remain until the unit’s receiver locates a time signal.
The clock's receiver will search until a signal is found, scanning rapidly through 72MHz channels. The receiver searches for a signal for 1 minute and then switch to scanning in 30-minute intervals until it has received a signal. Normal operation begins once a signal is received.
