ScreenMaster SM1000, SM2000 and SM3000
Paperless recorders
Replacing the battery
1 Introduction
This publication details the replacement of the battery (B11845)
fitted to the main board of ScreenMaster SM1000, SM2000 and
SM3000 paperless recorders. The procedure must be carried
out by a trained technician.
The battery is non-rechargeable and its only function is to
supply power to the recorder’s real-time clock when the
recorder is isolated from the power supply. It can supply power
to the clock for a minimum of 1.5 years before replacement is
required.

CAUTION
The recorder is vulnerable to electrostatic damage. Wear an
anti-static strap or dismantle the recorder on an anti-static
workbench.
Remove the main board as follows:
1 Isolate the recorder from its power supply.
2 Remove the recorder from its case – see Figure 1.
Note. Refitting is the reverse of removal.
Withdraw the recorder

Notes.
1. To disconnect the display flex-circuit, it may be necessary to remove the I/O module board in Slot D (if fitted).
2. SM2000 main boards manufactured before March 2005 have a 4-pin tochscreen flexi-circuit and a 4-pin connector block. Main boards
manufactured from March 2005 onwards are fitted with a 6-pin connector block. When reconnecting the touchscreen flex-circuit to a
main board equipped with a 6-pin connector block, ensure it is connected to the 4 pins nearest the front of the recorder.
Caution. When fitting a main board, ensure it
locates correctly in the lugs on the chassis
base.
