Important Information
Read this user’s manual carefully before use and retain for future reference.
The XW-IS4 warranty may NOT apply to below cases:
■ Repairs or product modification and alterations executed by unauthorized service personnel.
■ When damages caused by accidents include but not limited to lightning, water or fire.
■ The power input voltage used is not in the specified range (100-260V AC, 10-20V DC).
■ The serial number on the product has been altered, deleted, removed or made illegible.
Safety Precautions
TO AVOID RISK OF ELECTRICAL
SHOCK, DO NOT ATTEMPT TO
OPEN THE UNIT BY YOURSELF.
FOR ANY ASSIST,
PLEASE CONTACT YOUR LOCAL
DISTRIBUTOR OR PRO-X.
■ Turn off the power switch before connecting the unit with other equipment.
■ Before using an external power supply, always check that the voltage is within the
specified range and that the polarities of the connector are correct.
■ Do not use the unit in high moisture environment, which may cause electric shock
or fire. Turn off the power switch if any liquid gets inside it.
■ Do not place the unit on an uneven surface, which may cause the unit fall.
■ When the unit is left unused for a long period of time, disconnect it from power
source, and take the batteries out from IS-HS/IS-BP. Always disconnect the power
cord from power outlet when not using. This reduces the risk of electric shock or fire.
■ Do not use the unit near any heat sources such as radiators, heat registers,
stoves, or other devices (including amplifiers) that produce heat.
■ Clean the unit only with dry cloth.

Troubleshooting
1.Check if antennas of Base Station are loose or broken
and be sure they are installed in the right way
2.Check if the battery power of IS-HS/IS-BP is exhausted
3.Check if the working distance between Base Station and
IS-HS/IS-BP is within 250m LOS, if so, shorten the
distance and try again
4.Check if there is any high voltage or high power equipment
or high intensity magnetic field nearby
5.Check if there are obstacles, large metal objects between
Base Station and IS-HS/IS-BP
6.Try to restart the set
7.Try another frequency point and restart the set
Solutions
1.Make sure AC power cord is well inserted in a functional
power outlet
2.Check if the fuse under AC IN is broken
1.Check if the power switch is on
2.Check if installation of IS-HS/IS-BP batteries is right
3.Check if batteries are exhausted
1.Check if Tally indicator plug is inserted in the socket well
and steady
2.If the set works with a Switcher, check if the connection
of cables is correct
1.Check if IS-HS/IS-BP is registered on Base Station
2.Check if the set work on the same frequency point
3.Check if the battery power of IS-HS/IS-BP is exhausted
4.Be sure the volume of IS-HS/IS-BP is not at minimum
5.5.Check if HEADPHONE/SPEAKER selector switch is
in the right position
6.Check If working distance is more than 250m LOS,
if so,shorten the distance and try again
Fault
Base Station cannot be
turned on
The working distance
being less than 250m
or communication quality
being bad
Malfunction of connecting
or intercom
IS-HS/IS-BP can't get Tally
signal from Base Station
