Vincent,

Go to https://astro-physics.info/index.htm?tech_support/tech_support , look in Keypad Manual and Technical Documents, you probably need to put a new battery in the keypad and possibly upload the database.

Onderwerp: [ap-gto] Problem keypad

Hi from France

Sometime, i have a problem with the keypad of my very old AP 900GTO (bought in 1997!!).

The keypad often blink and restart with a small sound like "pop"...

The back-light off the keypad buttons also disappear, must i open the keypad for verifiyang cable and else?

regards

Vincent
