Using the dual wireless conferencing system
The conferencing pods in the dual-pod conferencing system function only with their associated base
unit.The base unit and conferencing pods are programmed at the factory and have matching serial
numbers: the serial number for the base is found on a label on the back of the base and the serial
number for the pods is found on a label on the bottom of each pod.
There are a few minor differences between single-pod and dual-pod operation, as detailed in the
following paragraphs.
Answering a call
• Both pods ring during an incoming call. Each pod's ringer melody and volume depends on
that pod's settings. Pressing ON/OFF on either pod activates both pods.
During a call
• Changing the speaker volume, and muting or unmuting the microphone, causes both pods to
change simultaneously.
• If one pod loses its link to the base due to low battery power or being moved out of range,
the call will continue on the other pod.
Ending a call
• Pressing ON/OFF on either pod ends the call and places both pods into standby mode, ready
for another call.
Caring for your NEC Max Plus Conference Unit
• Follow all warnings and instructions marked on your NEC Max Plus conference unit.
• Unplug base unit and conferencing pod from the wall outlet before cleaning.
• Do not use liquid or aerosol cleaners. Use a damp cloth moistened with water to clean the outside
of your conferencing pod or base unit and power supply.
Electrical considerations
• Use only the power adapter that comes with your conferencing phone.
• Use only the battery pack that ships with your phone.
Troubleshooting
If you are having trouble with your NEC Max Plus, it might be improperly set up or
other equipment might be malfunctioning.To begin, check for the following or consult
the chart on the next page:
• The NEC Max Plus base unit is plugged into the proper volt electrical outlet and its power light is
on.
• The battery pack in the pod section is fully charged and plugged in correctly.
• The telephone cord from the base unit is securely connected to the telephone wall jack.
• The equipment the other party is using is comparable in quality to your NEC Max Plus confer-
encing phone and is working properly. While the NEC Max Plus works with lower quality prod-
ucts, the quality of the conference will be impacted if the party you are conferencing with has
poor quality equipment.

Appendix Compliance
FCC Part 15/ICES-003 Compliance
This equipment has been tested and found to comply with the limits for a Class A digital device, pur-
suant to Part 15 of the FCC rules and Industry Canada ICES-003. These limits are designed to pro-
vide reasonable protection against harmful interference when the equipment is operated in a com-
mercial environment.This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may cause harmful interference to
radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference, in which case the user will be required to correct the interference at his/her own
expense.
Operation is subject to the following two conditions: (1) This device may not cause interference, and
(2) This device must accept any interference including interference that may cause undesired
operation of the device.
Changes or modifications not expressly approved by NEC could void the equipment warranty.
FCC Part 15 Subpart C/RSS-210 Noise
Electrical pulse noise is present in most businesses at one time or another. This is most intense dur-
ing electrical storms. Certain kinds of electrical equipment, such as light dimmers, fluorescent bulbs,
motors, fans, etc., also generate pulse noise. Because radio frequencies are susceptible to this, you
may on occasion hear pulse noise through the speaker, this is usually only a minor annoyance and
