HUNTER OPERATION
SECTION
2.8
2.8.5
2.8.6
The text screen contents are preserved and not affected by the
warnings. Following power restoration, the screen is restored
to its pre-warning state.
b) Graphics Mode
When a low battery is detected, the top line of the screen
displays:
* WARNING BATTERIES ARE LOW *
in reverse video and using the smallest character set (CHARO).
This message stays on the screen between battery warnings.
HUNTER also bleeps twice. The warning message destructively
overwrites the top line of the screen, the contents of which are
lost and must be restored by the user's program.
If an attempt is made to use HUNTER without replacing or recharging
the batteries, Battery Low warning is displayed and HUNTER
immediately turns off again. It is worth commenting that flat
batteries can partially recover after being switched off such that
operation could continue for a short period. It is not recommended
that this should be done in practise, particularly with rechargeable
batteries which could then become totally exhausted. In the case of
Ni~Cd batteries, this can lead to permanent damage to the cells.
POWER SAVE
An automatic power conservation system has been incorporated into
HUNTER, enabling the power to be removed from circuits when they are
not in use.
Usually, the computer will enter power save mode whenever it is
awaiting a keyboard entry. However, a few programs defeat this
facility by not using standard CP/M console calls and have a
correspondingly higher overall power consumption. Please consult
Husky Computers for advice in specific cases.
BATTERY CHARGING
HUNTER is optionally available with rechargeable cells and a mains
(line) powered charger.
This arrangement allows cells to be recharged in HUNTER, and for
alkaline cells to be quickly substituted if the user forgets to
recharge!
But BE CAREFUL -
NEVER connect the charger when alkaline batteries
