Select a number in mAh that is no more than 80% of the battery capacity. When the battery
capacity used reaches this value an alert message will be announced. If the field is left at 0 no
alarm will be announced. You have to remember to reset the battery capacity after recharging the
battery.
Connections
Under the rubber flap on the bottom right corner are a
number of connections.
At the bottom is the Audio headphone connection for an 8
to 32 ohm headset. Next up is the SD card slot. Just
above the SD card you can see the mini USB port
mounted on its white coloured circuit board. This is used
for connecting a cable to a USB port on your computer. It
does not provide power to the radio. Above that is the
battery charging jack. This is a 2.1 mm jack with the centre
positive.
There is a tiny round recessed button on the left of the
USB port. DO NOT PUSH THIS BUTTON as doing so will
erase the transmitter firmware. If this button has been
pressed see the topic “Restoring a ‘Bricked’ Transmitter
with SAM-BA” in the manual Communicating with a
Computer.
SD card
Included with your transmitter is an SD card. This is a
micro memory storage card is about the size of a
fingernail. It fits into a slot in the lower right corner of your
transmitter under the rubber cover, between the
headphone jack at the bottom and the mini-USB port in
the middle. It is inserted with the gold contacts facing
upwards.
It is easier to feel the card than see it when installed. It
pushes into place and locks into a detent. To remove it,
push it in again and it will be released from the detent.
To read or write to the card with a computer, it can be
inserted into a holder which fits a USB port, or it can be
slotted into a card reader. The card will then appear on
