Preliminaries
If the transceiver has not been used since leaving the factory, fully charge
the battery using
VAC-520
Rapid Desktop Charger before using it.
Mount the battery on the transceiver as described and shown in the il-
lustration below. Also, install the antenna on the jack on top of the trans-
ceiver by screwing the connector into the jack until it is finger-tight.
Battery Removal & Replacement
Make sure that the
VOL
control is set into the “off” click-stop (fully
counter-clockwise, and remove the protective soft or hard case, if used.
Grasp the transceiver with your left hand, so your palm is over the
speaker and your thumb is on the Battery Release Button.
Move the Battery Release Button in the
direction indicated by the arrowhead,
while using your right hand to slide the
battery pack toward the side with the
button. The battery pack should slide
smoothly out of its track.
To replace the Battery Pack, repeat the
second and third steps above, simply
sliding the battery case in the other direction after aligning the short-
er side of the Battery Pack with the track below the Battery Release
Button.
WARNING
The
FBA-19
was designed as a backup battery pack, and it
can be used to power the transceiver if you are in an area that
does not require the use of an intrinsically safe radio.
The
VX-537IS
is only intrinsically safe with the use of the
FNB-29AIS
,
FNB-29ANIS
,
FNB-29ALNIS
, or
FNB-
29BNIS
battery pack.
Do not reverse-connect the battery terminals.
Do not parallel-connect the battery terminals.
Do not change batteries in hazardous locations.
To reduce the risk of explosion, recharge the batteries outside
of hazardous locations.
