OPERATING THE LOCK:

Your ESL10 Electronic Safe Lock w/ 202A Protex Keypad has a factory
combination of: * - 1-2-3-4-5-6-#
To open the lock, simply press the "*" key to clear and wake up the
electronics. Now press the keys of the combination one at a time and
finish with the "#" key.
If the combination is keyed correct, you will hear a click and the LED
will lit (RED).
You have 3 seconds to open the door before the lock will relock itself
automatically.
Here are a few things to remember:
a) With each keystroke the red lamp on the keypad will flash and a
chirp will be heard.
b) If 4 (four) incorrect combinations are entered, the lock will go into a
"Penalty Lockout Mode" for 15 minutes to prevent trial and error
manipulation attempts at opening the lock. The red lamp will flash
once every 5 seconds during the penalty period, the red lamp will
flash with a chirp 8 times rapidly to indicate the lockout condition.
c) Always make sure to replace batteries with good quality fresh
Alkaline 9 volt batteries. It is recommended to replace the batteries
once a year to prevent corrosion damage from leakage.
d) If the batteries die, you can use the override power cord to power-
up the lock. Just insert the two prong plug into the small outlet
below the keypad (right under the PORTEX logo) then connect a 9
volt battery to the connector. The internal memory of the lock will
keep your combination in memory even if the batteries are dead or
removed.
e) During a sequence, if you make a mistake, you can press the "*"
key to clear the last input and start over again.
f) At any time during opening or combination changing the unit will
register the first 5 numbers of the combination into the "buffer" that
th
receives input. The 6 number will be the last numeric key pressed.
For example, if you press *1-2-3-4-5-6-7-4-5-2-7-6# the program
recognizes only the *-1-2-3-4-5-6-# input. The last numeric key
pressed continues to replace the one prior until the # key is
pressed to indicate completion. This is a security feature that
allows you to baffle an on-looker that maybe trying to
memorize your combination by standing behind you.
So basically you press the first correct 5 digits, followed by any fake
numbers that you make up and end it with the correct 6
by the # key.
