oPening and Closing YouR gto KeYPad

for all keypads

Please note that photos show the inside of a keypad with serial # 1568gto or higher. earlier keypads

will look different on the inside, but the procedure for opening and closing the keypad is the same.

Warranty considerations: the manufacturer warrants the astro-Physics gto Keypad for three years. if your keypad

is still within the warranty period, you may void the warranty by opening the keypad. if you are unsure of the keypad's

purchase date, jot down the serial number and call astro-Physics.

Remove the KeYPRo silicone-rubber keypad protector. for

instructions, see the previous document.

1. lay your keypad face down on your work surface. You will need

a Phillips screwdriver, size #0. locate the six screws that hold the

two halves of the keypad together (arrows at right).

2. Partially remove the screws. be careful not to strip the screw

heads. the screws do not need to be removed completely.

Just back them out until you feel that they are no longer

engaged.

Be very careful separating the front and back of the

keypad. In particular, pay attention to the cable strain

relief, and be careful that the display circuit board does not

catch on the screws. The display should remain with the

front half of the keypad. Also, see note below on spacers.

3. open and place the back case cover along the side without

straining the speaker wires. You may leave the speaker wires

plugged in.

be careful not to lose the six

spacer washers. some may

stick to the circuit board instead

of staying on the screws. it is

best to place the spacers onto

the screws right away. this will

keep you from losing them, and

it makes lining things up easier

when reassembling.

these spacers are vital for

maintaining separation between

components, and to avoid dam-

age to the case.

do not omit!
