59 MCG-2 Micro Character Generator
BATTERY REPLACEMENT:
Your MCG-2 uses a 3V Lithium watch battery (BR2325/CR2325 or
equivalent). This battery should last 10 years (3 years if RTC is
installed). Battery replacement is indicated by one or more of the
following:
1. A “flashing power LED” condition whenever the unit is
powered up.
2. Time and date (with the RTC option) and buffer information is
not correctly maintained when power is off for any length of
time.
3. Baud rate and other settings not correctly maintained when
power is off.
If you take care in replacing the battery, with the Power On, then none
of the stored data will be lost.
To replace the battery, proceed as follows:
1. Remove the two screws on the face of the unit.
2. Gently pull the front cover plate forward and down.
3. Slide the top cover forward and remove.
4. The battery is silver, about the size of a quarter, and is sitting in
a black holder. Using a small screwdriver, gently remove the
battery, being VERY careful not to over bend the metal tab
holding the battery in place.
5. Locate the plus symbol (+) on the new battery and insert the
new battery plus (+) side up. BE VERY CERTAIN THAT THE
PLUS (+) SIDE IS UP.
6. Reassemble the unit being careful not to over tighten the
screws. (Do not tighten more than 1/8 turn past seated).
The battery may be replaced with the power on to maintain the buffer
data, and date and time (with the RTC option).
