8545-M838-O1 Rev D 825 Installation & Technical
KEYPAD FUNCTIONS
The Model 825 indicator has an interactive (Touch Screen) display, a full “QWERTY”
alphanumeric keypad and four navigation keys with an interactive ENTER key. The keypad
and touch screen are used to enter commands and data into the indicator. This section
describes each key along with its normal function. Refer to Figure No. 20 or the actual
indicator while reading this section.
WARNING! The membrane keypad is not to be operated with pointed objects
(pencils, pens, fingernails, etc). In addition, the interactive touch screen is
glass (fragile) and should not be operated with pointed objects and with
excessive force. Damage to the keypad and touch screen resulting from this
practice is NOT covered under warranty.

ON I/OFF KEY
Pressing the ON/OFF key when the 825 is off will turn the indicator ON. If the indicator is
already on, you must press and hold the ON/OFF key for about four (4) seconds to turn
the indicator OFF.
IMPORTANT! If the auto power-on jumper has been installed (across pins 2 and 4 of P13)
whenever AC power is applied to the indicator (or the AC cord plugged in), it will turn on
automatically without pressing the ON/OFF key.
