BATI'ERY - RECHARGEABLE
Only Nickel-Cadmium (Ni-Cd) cells are to be used. Under no
circumstances must any other type of rechargeable cell be installed.
We recommend Berec type NCC50 cells of 500 mAH capacity.
Low Battery Warning
HUNTER is designed to provide adequate warning of impending battery
failure and will protect user's data, even in the worst situations.
This warning facility has been improved in Hunter operating systems
Ver. 9G onwards.
When HUNTER's batteries become low, HUNTER will give warnings to the
user. Since it is usually essential that all data and programs are
secured, it is recommended that HUNTER is switched off as soon as
practicable and the batteries either replaced with a fresh set or, if
rechargeables are fitted, put on charge.
Low Battery warnings are repeated as follows:
a) every 5 seconds if the HUNTER is switched on, but quiescent,
b) after every keyboard key depression
or,
c) every 0.5 seconds if characters are being received on the RS232
port.
If ten consequentive warnings are ignored, HUNTER automatically
switches
SJff., When this occurs, HUNTER is placed automatically in a
CONT mode (see section 3,4,3,4). This means that when power is
restored, program execution will continue from precisely where it was
prior to the interruption.
HUNTER has two screen modes, text and graphic (see section 2.5).
Battery low warning is slightly different in the two modes:
a) Text Mode
When a low battery is detected, the top line of the screen
displays:
* WARNING BATTERIES ARE LOW*
HUNTER bleeps twice and then the original text is restored until
the next warning.
