REPLACEMENT OF THE BATTERIES
When the digital selector range is significantly reduced and/or 10 rapid
beeps are emitted when switched on, this means that the batteries are flat
and require replacement. The digital selector contains two CR2430 lithium
batteries.
If the DS100 is used in freezing temperatures (below -10°C) flat battery
signals may be given even if the batteries are still partially charged.
To replace the battery, proceed as shown in fig. 3.
