Keypad Protector
The Keypad protector is a heavy-duty molded rubber casing with a full 1/4” thickness on all impact surfaces. If you
accidentally drop your Keypad, the rubber casing will absorb much of the blow. Your display, Keypad, electronics and the
case itself will be protected from damage. In addition, the rubber prevents the Keypad from sliding when placed on a table
or other at surface and the Keypad will feel secure in your hands as your observe. The KEYPRO also offers protection
during transport and storage.
Installation:
Caution: The KEYPRO ts closely around the Keypad controller. You must work it gently into place. If you force the
rubber casing while it is being installed on your Keypad, you may tear the rubber.
1. Insert the connector and thread the cable through the opening at the bottom of the KEYPRO. Do not insert the cable
and the bottom of the Keypad all the way at this time.
2. First, insert the top portion of the Keypad (the display end) into the KEYPRO.
3. Second, gently work the bottom portion with the cable connection into place.
Keypad Care and Warranty
Warranty
Keypad: Three (3) years parts and labor.
Battery: 90 days.
The Keypad manufacturer warrants that the product is free of defects in materials and/or workmanship from the date
of shipment for a period of three years. This warranty does not apply to any products which have been subject to
misuse, accident, alteration or if the unit has been serviced by anyone other than an authorized representative. During
the warranty period, the manufacturer will, at its discretion, (1) repair the product to full working order; (2) replace the
product with a comparable product. Replacement products will be new or serviceably used, comparable in function and
performance to the original product. The product will be warranted for the remainder of the original warranty or ninety (90)
days from the date of shipment of the product, whichever is longer. DO NOT open a Keypad that is within its warranty
period or you may void the warranty!
Keypad Battery for 256K Memory Boards
Keypads with serial number 1565GTO or earlier that have the original 256K circuit board have a 3V Lithium battery that
powers the memory so that information is retained from one session to the next. Battery life is estimated 5 years at room
temperature. You can purchase replacement batteries from Astro-Physics (part # E0310) or from alternate sources.
Instructions for replacement are in the Technical Support section of our website. Battery Number: CR1632
Keypad Battery for 512K Memory Boards
This includes Keypads with serial number 1568GTO or later (and some earlier Keypads that have been repaired or
upgraded with a new 512K memory board). These Keypads also have a 3V Lithium battery with an estimated life of 5
years at room temperature. However, this battery has been wired into a special assembly, so the replacement battery
must be purchased from Astro-Physics (part # E0334), but it can be installed by the customer. If the battery fails within the
3-year warranty period, it is best to have the manufacturer replace it. Opening the unit to replace the battery within the rst
three years may void the warranty.
Cleaning Keypad Display
The display window is made with a Mylar material. It is recommended to use a commercial glass cleaner to wipe down the
display. Spray the cleaner on a cloth and rub the display lightly. Do not use solvents of any kind. Note: It is a good idea to
leave in place the protective plastic cover that ships with the Keypad, it will extend the display window’s lifespan.
Temperature Ratings
The real time clock, battery-backed RAM, Extended Temperature Vacuum Fluorescent display, and backlit panel are all
rated to –40 degrees C (-40 degrees F).
