Introduction
Congratulations on the purchase of your 940H Student Microphone. Using a student
microphone is a great way to encourage student participation. Your 940H Student
Microphone should only be used with your FrontRow Pro or FrontRow Pro Digital
classroom sound system.
Read this manual carefully to become familiar with your 940H Student Microphone
to get the most out of your system.
Your 940H Student Microphone and 940C Charger use SmartCharge technology.
The microphone will only charge the "silver-sleeve", auto-sensing battery that
comes with your microphone. If an incompatible battery is detected, the
microphone will not let you charge the battery.
You may use standard alkaline batteries in your 940H Student Microphone if you forget
to charge the unit, but do not attempt to charge alkaline batteries. To ensure proper
charging, always be sure that only "silver sleeve" auto-sensing batteries are installed.

1. Avoid Abuse to the Charger
To reduce risk of electric shock, unplug
the power supply from outlet before
attempting any maintenance or cleaning.
Turn off controls will not reduce this risk.
DO NOT disassemble the power sup-
ply or charger. Return the apparatus
to Phonic Ear Front Row for qualified
service and repair if service or repair
is required. Incorrect reassembly may
result in a risk of electric shock or fire.
DO NOT expose the power supply or
charger to rain, snow, water, gas, oil, etc.
DO NOT operate the power supply or
charger if it has received a sharp blow,
been dropped, or otherwise damaged
in any way; return the apparatus to
Phonic Ear Front Row for qualified ser-
vice and repair.
DO NOT block or cover the apparatus
and impede ventilation.
2. Proper Use of the Power Supply or
Charger and Wiring
An extension cord should not be used
unless absolutely necessary. Use of
improper extension cord could result
in a risk of fire and electric shock. The
cord MUST be plugged into a grounded
outlet. Make sure it is properly wired, in
good electrical condition, and wire size
is large enough for AC ampere rating of
the power supply or charger as specified
below. AWG = American Wire Gauge.
To reduce risk of damage to plug and
cord when disconnecting the power
supply or charger, ALWAYS pull on plug
- NEVER on cord.
Locate cord so that it will not be
stepped on, tripped over, or otherwise
subject to damage or stress. DO NOT
lay extension cord on charger.
DO NOT operate the power supply
or charger with damaged cord or
plug - replace them immediately.
