Function Keys

Battery Compartment

Battery Cover

1. Slide the battery cover off as indicated by the triangle to open the battery compartment.

2. Insert 1 x AA battery, observing polarity.

3. Replace battery cover.

4. Upon power-up, the alarm will sound once and all LCD segments will light up briefly.

5. The clock will now start searching for the WWVB time signal and the radio tower icon will flash to
indicate signal reception attempt. Do not press any buttons at this time.

6. Reception typically takes 6-10 minutes during ideal reception time (nighttime hours) and will timeout
after 10 minutes if no signal is found.

7. Upon successful reception, the time and date will be set to absolutely accurate time (default to
Eastern time zone).

8. In the case of no reception keep in mind that for most locations reception during daylight hours is
not possible. In this case, you may manually set the time or simply wait overnight.
