Krown Manufacturing PCM3512 - Manual (Page 19)

CHAPTER 6 (CONT.)
• Clean the PocketComm by wiping the unit with a damp cloth to keep it looking
new. Do not use harsh chemicals, cleaning solvents or strong detergents to clean
the PocketComm.
• When replacing batteries, use only Rechargeable NiCad AAA batteries. Do not use
alkaline batteries with the AC charger connected. Batteries may explode or leak and
cause permanent damage to the Pocketcomm.
TROUBLESHOOTING YOUR POCKETCOMM
The unit will not turn on:
• Plug the AC charger and turn the unit on. If the unit is on, the batteries need to
be fully charged. Turn off the unit and let the battery charge for at least 6 hours
before use.
• If the unit will not hold the power after fully charged, replace the rechargeable
NiCad batteries.
Not receiving or sending:
• Check status of the unit for correct mode settings. VCO mode needs to be off in order
to work in acoustic coupling. It will disable the internal microphone and send the
output to the rear speaker.
• Check and firmly plug the cable to the PocketComm and the mobile phone.
• If the call is dropped out (fade out), hang up and redial the number.
Receiving garbled messages:
• It may be caused by lost, damaged or late signals sending through the air to the
receiver. It happens with any wireless call, even non-TTY calls. This is mainly caused
by nature. Move your PocketComm and mobile phone to where you can receive a
strong signal. If you use a cordless phone, switch to a different channel or move
closer to the base to strengthen the signal. Check and see if you have a good
connection from the cable to the PocketComm and the mobile phone.
Feedback noise:
• If you use the PocketComm and the signal LED is ON constantly, your PocketComm
is getting a feedback. You may reduce the volume of your mobile phone down until
the LED light turn off and then increasing back for better receiving.
• Move the mobile phone away from the PocketComm and touch firmly the antenna to
reduce the feedback.
