Alkaline Battery Tray Installation
The
supplied
SBT-12
Battery Tray allows operation
of the
FTA-450L
using six “AA” size alkaline battery
cells.
When installing a cell, insert the (–) end rst, then
press in the (+) end so the cell snaps into place. Pay
attention to the polarity indicated inside the case.

Alkaline Battery Tray
The SBT-12 must not be used with re-
chargeable cells. The SBT-12 does not con-
tain the thermal and over-current protection cir-
cuits required when utilizing Ni-Cd and Ni-MH
cells.
Note: Replace all six cells at the same time in case of
low battery.
To install the
SBT-12
, remove the Lithium-ion bat-
tery pack first from the transceiver, turn the open
side of the
SBT-12
down, then insert it into the bat-
tery compartment.
Note: Be sure that the rubber gasket on the
SBT-12
is not loose when inserting.
Low Battery Indication
As your battery discharges during use, the voltage will
gradually become lower. When the battery voltage
reaches 6.0 Volts, the “ ” icon will blink on the
LCD display, indicating that the battery pack must be
recharged or the alkaline battery cells must be replaced
before further use.
Avoid recharging Lithium-ion batteries before the
“Low Battery” indicator is observed, as this can
degrade the charge capacity of your Lithium-ion
battery pack. YAESU recommends that you carry an
extra, fully-charged pack with you so you will not
lose communications capability due to a depleted
Lithium-ion battery.
The fully-charged battery lasts for 13.5 hours on the
FTA-450L
under the conditions below:
