identifying Your Keypad battery

Please note: Previous instructions that were published on the web were written before internet-based downloading of

the database was available. it was therefore recommended that you leave your keypad powered up during the battery

replacement so that the database would not corrupt. it was felt that the risk of damage posed by working on a "live"

keypad was worth it to prevent the necessity of returning the keypad to us for a database reload. this also assumed that

the battery was being replaced as a preventive measure before the database actually corrupted. experience has since

taught us that batteries are rarely replaced before the database has corrupted. We now also have the database loader on

our website so that you can easily reload the database yourselves.

With these factors in mind, we now strongly recommend that you not have your keypad powered up during this

procedure. the risk of damage to the sensitive electronics is too great. (at 12 volts, there was never any danger to

personal safety.)

We are also recommending a somewhat different method of battery removal from the one previously published. again,

experience and experimentation have given us a better approach to removing and reinserting the battery without damaging

the battery carrier. if you are familiar with the previous method, please take note of the new procedure outlined below.

Remove the battery

1. unscrew the six screws in the corners on the back of the

keypad with a #0 Phillips screwdriver. the screws do not

need to be removed completely.

more detailed instructions on opening and closing the key-

pad are referenced in a previous section.

2. carefully open the keypad, taking care to make sure that

the white nylon spacer-washers on the screws are not lost.

they are important safeguards for both the electronic com-

ponents and the case! lay both halves of the keypad with

the wires still connected flat on your work space.

3. locate the cR1632 battery in its clip holder on the circuit

board. You may wish to unplug the display's ribbon cable,

and possibly the blue plug just to the left of the battery be-

fore changing the battery. it is not necessary to do so, but it

does give you more room to work. be very careful that you

don't damage the ribbon cable, and take note of exactly how

everything is plugged in so that you put it all back correctly.
