If your Clock is not powered for more than 2 years, this will cause
the battery maintaining the time in the Real-time Clock IC to go
flat.
In order to change the Real-time Clock's coin cell, you will need:
- A Flat screw-driver
- A 5.5mm socket and driver (optional)
- A BR2325 Coin Cell
|
| 1. Turn the power to the CapeClock off. |
| 2. Remove the CapeClock from the wall (if you
have already mounted it) by loosening the two mounting screws
at the bottom of the clock sufficiently to remove the clock
off the bracket that is mounted on the wall. Take care, because
when the clock is pulled from the screws holding it to the
wall-mounted bracket, it will have nothing holding it up.
To remove it from the wall-mounted bracket completely, gently
lower it, taking care that any wires that are already connected
are not strained. |
| 3. Place the CapeClock face-down on a protective
cloth so that the readers and front are not scratched. Remove
the Back-plate by removing the 4 galvanized nuts that keep
it attached to the CapeClock box. |
| 4. Remove the coin cell from its holder (you
can gently prize it out with a flat screw-driver) and insert
the new coin cell. |
| 5. Attach the Back-plate to
the CapeClock box using the 4 galvanized nuts. |
| 6. Replace the CapeClock back
onto its wall bracket, ensuring that the tongue of the back-plate
is inserted into the corresponding groove in the wall-mounted
bracket. Secure the CapeClock onto the wall-mounted bracket
(see Figure 3) with the 2 Mounting screws at the bottom of
the CapeClock, ensuring that the cable cover plate (see Figure
4) is correctly positioned.
