I Battery Case; I External Power Operation - Icom IC-T90A Instruction Manual

I Battery case

q Install 2 R6 (AA) size alkaline
batteries into the optional
BP-216 .
BATTERY CASE
• Be sure to observe the correct
polarity.
w Install the battery case as
shown at right.
A build in step-up convertor in
the BP-216 increases the volt-
age up to 5 V DC.
Keep battery contacts clean.
It's a good idea to clean bat-
tery terminals once a week.
D Battery information
The batteries may seem to have low capacity when used in
low temperatures such as +14 °F (–10 °C) or below. Please
keep the battery case or pack warm in this case.
D Battery replacement
When the batteries become exhausted, the function display
may blink or have a lower contrast. In these cases, replace
all batteries with new, same brand, alkaline batteries.

I External power operation

An optional cable CP-19 (for 12 V cigarette lighter socket) can
be used for external power operation.
Power supply range is between 5.5–11.0 V DC.
. •
NEVER CONNECT OVER 11.5 V DC directly into
the DC power jack of the transceiver.
• BE SURE to use CP-19 when connecting regulated
12 V DC power supply.
• If a battery pack is attached, the voltage of the external
power must be within 11.5–16 V DC, otherwise, the bat-
tery power may be used for operation.
• The maximum output power is 5.0 W regardless of the
power supply voltage.
• Remove the cables from the transceiver when not using
it. Otherwise, the vehicle battery will become exhausted.
