3.4. Low Battery Indication
The unit continually monitors the battery level during use. A warning is
provided when the remaining capacity of the battery reaches approximately
10% of the full capacity. The warning is in the form of two short beeps of
high and low pitch in Speech and Tone Modes or three very short vibration
pulses and is provided at the end of each denomination announcement.
When the remaining capacity of the battery reaches approximately 5% of
the full capacity, the warning tone changes to four short beeps of high and
low pitch at the end of each denomination announcement. In Vibration
Mode, this warning is in the form of three very short vibration pulses. The
5% and 10% warnings are the same in vibration mode.
If the battery level is deemed to be critically low and insufficient to permit
accurate operation, the unit emits 3 short beeps of different pitch or three
short vibration pulses and shuts itself off. This can happen when the unit is
first switched on or when the volume or output modes are changed. If one
of the buttons is kept pressed when the battery is critically low, the unit will
emit an intermittent series of beeps. You should not attempt to operate the
unit once it starts giving critical low-battery warnings and should
immediately replace the battery with a fresh one.
Battery Warning and Volume Level
Battery life and low battery warning signals are highly dependent on the
output mode and volume level at which the device is being operated. You
may therefore get low-battery warnings at volume level 3 for instance, but if
the volume level is adjusted to lower levels, the warnings may stop. This is
because higher volume levels and Vibration Mode consume more power
When the battery weakens, the unit will automatically reduce the volume
level in Speech Mode to allow continued use and to extend the life of the
battery. Therefore, even if you attempt to set a higher volume level, the
unit will limit the volume to the maximum level possible with the weak
battery. To restore full volume, the battery must be replaced.
If there is no beep or vibration indication upon pressing one of the buttons,
it is likely that the battery is too weak and should be replaced.
