What is meant by Mapping Handsets

Each receiver has a unique ID as shown on the receiver ID label. All handsets are locked into

communicating with a receiver. If you want to lock a handset to work with a different/new

receiver you must press and hold down the “?” key until the handset has mapped. This can take

several seconds. When you see the up/down arrows flashing on the handset LCD, the handset

is locked to the new receiver. Please note that when locking handsets the distance between

handset and receiver should be a approx 50-75mm.
