Installing the
Handset
The PRC1077 manpack configuration uses the MHS handset, which is either a
H-189/U or H-250/U military handset.
To install a handset on the PRC1077 front panel (
refer to the figure on page
3-1
):
1. Remove the rubber cover from the dual Audio connectors on the
transceiver front panel.
2. Place the handset connector onto the AUDIO connector. Turn the knurled
connector until the alignment pins engage with the audio connector slots,
then push in and twist clockwise. The flat side of the handset connector
should face the top of the PRC1077 transceiver.
