Power Supply
[ 1 ] Power supply
Driven by 6 batteries
Optional AC line adapter (9.5 VDC, 1.3A)
available
[ 2 ] Battery type
6 alkaline batteries (LR6)
[ 3 ] Service life of batteries
Will last through one tape cassette, and then
some. (at room temperature and normal
humidity)
[ 4 ] Automatic power off
Yes
(If the machine remains unused for approx. 5
minutes, it automatically powers itself off.)
[ 5 ] Low Voltage and High-voltage input detection
(1) Low voltage detection when dry batteries are loaded:
- During printing
If the voltage level at the CPU's A/D terminals drops below 6.4 V or 6.0 V twice
in succession, the "BATTERY WEAK" or "BATTERY EMPTY" message
appears on the LCD, respectively.
If the voltage level at the CPU's A/D terminals drops below 5.8 V twice in
succession, the CPU immediately shuts down the power.
- During non-printing
If the voltage level at the CPU's A/D terminals drops below 6.9 V, the CPU
immediately shuts down the power.
(2) High-voltage input detection when a high-voltage AC adapter is connected:
If a commercially available high-voltage AC adapter (15.1 V or higher) is
connected, the CPU immediately shuts down the power.
CAUTION:
A commercially available high-voltage AC adapter cannot be used
for this machine. It is recommended that a Brother genuine adapter be used.
