Wearing the PSM
(See Figure 1)
To minimize interference and optimize PSM performance,
wear the radio and PSM so that the accessory cord will not
cross over or touch the antenna. Also, try to wear the radio
and accessory fairly close to each other to avoid strain on the
accessory connector.
Figure 1. Wearing the PSM
Note: For optimize PSM antenna performance,
wear the PSM antenna above shoulder
level.
