4.2.4.2. Charging Your Batteries
Equipment Connections. Each SW75T or SW70H1 transmitter comes
equipped with an SWC-POWR Tireless Wireless™ plug-in charger (see
Fig. 4l). In addition, each SW70H1 comes with its own battery-charging
mic clip (SWC70-CL). The SWC-POWR charger can be plugged directly
into either the transmitter or into the clip. A Sabine rechargeable battery
(SWBC1) will charge whenever the mic clip is connected to the Sabine
SWC-POWR charger and the handheld is properly placed within the
mic clip.
Charging Indicators. Much like your cell phone, the transmitters will let
you know the charging status of the battery. When the battery is charg-
ing, the battery meter will flash to indicate the relative level of the charge
— one, two, three or four elements will flash (see Fig. 4i).
Once the battery is fully charged, all four elements in the battery meter
will flash. This indicates that the charging circuit is no longer on (see
Fig. 4j).
NOTE: The right-side indicator segment will flash for several minutes
when charging is first attempted (see Fig. 4h). The lower the battery
level, the longer this initial “testing/not charging” flashing sequence will
continue. During this time, the Tireless Wireless battery circuit is evalu-
ating the suitability and charge status of the battery in place. When it has
completed its evaluation, it will either commence the progressive flash-
ing depicted in figure 4i (CHARGING), or continue to flash (TESTING/
NOT CHARGING). All segments flashing in unison signifies that the
battery is fully charged (see Fig. 4j).
These same indications will also be displayed on the receiver LCD,
and on the Remote Control Software screen.
NOTE: The Tireless Wireless battery charger will only charge NiMH
rechargeable batteries. If you place any other kind of battery in the
transmitter, and then attempt to charge it by connecting the charger, the
Tireless Wireless circuit will detect the type of battery and will not begin
charging. Again, the battery indicator on the transmitter will flash the
right-side element indicating testing/no charging (see Fig. 4h).
Battery Warnings. When the transmitter battery voltage drops below a
critical threshold, the battery icon (which normally displays the voltage
level) will begin to flash. This will occur on the transmitter and receiver
and is an indication that you need to replace the battery, or charge it by
placing the handheld mic in the charger clip. NOTE: Microphone will still
transmit audio when placed in clip. Alternatively, you can connect the
charger directly to the transmitter using the built-in charger jack located
on the side of the beltpack transmitter and near the antenna on the
handheld transmitter (see Fig. 4l). If the battery is not changed or re-
charged, the transmitter will eventually turn off (see Fig. 4k).
Transmitter Operation

Fig. 4h: TESTING/NOT
CHARGING
Right-side battery indicator
segment will flash to indicate
that the battery is being
tested. This occurs prior to
charging a NiMH battery and whenever a non-
rechargeable battery is placed on charge.
Charging is not occuring when indicator lights
in this fashion.
Fig. 4j: FULL CHARGE
Battery indicator segments
will flash in unison to indi-
cate that the battery is fully
charged.
NOTE: Battery can be left
connected to the charger and will receive pe-
riodic maintenance charging.
Fig. 4i: CHARGING
Battery indicator segments
will flash progressively start-
ing from the relative charge
state of the battery. This ex-
ample depicts a fully dis-
charged battery being charged. As the charge
progresses, left-side segments will remain vis-
ible as right side segments continue to flash,
until all segments are visible. At that point, all
segments will flash on and off in unison (see
Fig. 4j).

NOTE: When the battery has reached
a specific discharge level, the transmit-
ter will automatically
turn off, and the trans-
mitter LCD will display
the message at right.
