Provisioning the T7406 / 13 T7406 Installation Guide Powering the T7406 The T7406 design has taken into account the need to provide a reliably- powered cordless business telephone. The T7406 utilizes premium 1400 mAh NiMh batteries. A fully charged 1400 mAh battery should provide four to five hours of talk time in a typical eight-hour day over, approximately, a three-year service life. The T7406 has been engineered to provide the following talk-time parameters: T7406 users should feel comfortable using the handset for an entire workday without the need to put the handset back into the charger cradle for charging or topping up. Studies have shown that users have been able to get four to five hours of talk time from a fully charged 1400 mAh battery. Traffic studies have shown that typical users do not usually need more that three hours of talk time in an eight-hour day. If talk times exceed four hours or the product is to see use through multiple, consecutive shifts, multiple spare batteries are strongly recommended. Battery Charge Controller The T7406 incorporates a special handset battery charge controller that employs a four-stage charging program that sequences charging from a soft start to a fast charge, and then to a topping charge, followed by a maintenance charge. This four-stage charge sequence presents an optimum-charging plan that helps maximize the overall life of the battery by managing two critical elements in the battery charging process, the charge rate and overcharging protection. Note that NiMh batteries do not exhibit memory problems and it is not necessary to drain the batteries prior to recharging. Low battery status is indicated on the handset by the visual charge status on the display and/or the audible warning tone. The T7406 handset can be placed back into the charge cradle for charging when it is not in use.

The handset charge light will turn from red to green to indicate that the handset battery is fully charged and ready for use. The T7406 charge stand provides a rear port as a trickle charger that charges a fully depleted 1400 mAh battery in 12 to 14 hours.

Important battery pack information / 15 T7406 Installation Guide Impor tant batter y pack information Before you use the T7406 cordless handset, read the following information. This unit contains a rechargeable nickel metal hydride battery: Follow the proper installation and charging procedures for the T7406 battery pack. Refer to C harging the T7406 Battery Pack on page 24. The rechargeable battery pack must be fully charged before you use the T7406 handset for the first time. It takes approximately three hours to charge a standard 1400 mAh battery pack. It takes approximately 12 hours to trickle charge the spare battery in the charging cradle. Nickel metal hydride batteries are recyclable. You can help preserve the environment by returning your unwanted batteries to your nearest recycling center for recycling or proper disposal. Phone 1-800-8-BATTERY to locate a Battery Recycling Center near you. Wa r n i n g : The battery will explode if disposed of in a fire. Do not use the nickel metal hydride batteries provided with your T7406 cordless telephone with any other product. These batteries were designed specifically for use with theT7406 telephone and the T7406 charger ONLY. Improper use of the T7406 batteries may result in fire hazard. Do not do anything that would cause the battery to short circuit. Do not charge the battery with any charger other than the one supplied with this equipment. WARNING Nickel metal hydride batteries must be disposed of properly. Do not dispose of the batteries in office or household waste.
16 / About your T7406 telephone P0606142 01 About your T7406 telephone The T7406 is a multiple-handset, single-base cordless telephone system. The T7406 telephone provides a fully-integrated mobility solution for your business. The T7406 handset allows you to freely move around your work space while on a call, and still maintain access to all your telephone system features. The T7406 telephone uses advanced digital frequency hopping spread spectrum (FHSS) technology to provide a quality audio path over a 900 MHz radio link. Establishing a call over a radio link is comparable to a wire line communication. Note:The T7406 cordless telephone is supported on all Norstar systems (DR3 or higher) and on all Business Communications Manager systems. Radio range and coverage considerations The effective operating radio range in your facility depends on the building construction and the internal layout of the facility. Typically, a dense office or warehouse environment has an effective operating radio range of 95 meters (300 feet). An open office environment enhances operating radio ranges. Refer to Provisioning the T7406 on page 7. Security of Conversation Each base station has a unique Security Code (S.S. Code). All three handsets registered to the base station must share the same Security Code. Each of the three handsets assigned to a base station must also have a unique identification (Set I.D. 1, 2 or 3). Density and Interference For this system to be interference-free, install a maximum of two base stations and six handsets per location. Each base station provides three independent time compression multiplexing (TCM) line connections to the telephone system. Each base station uses half of the Industrial Scientific Medical (ISM) band for its frequency hopping channels. The dip switches on the base station allow you to assign the base station to use either the lower half (902-915 Mhz) or the upper half (915.1-928 Mhz).
About your T7406 telephone / 17 T7406 Installation Guide Each base station must use a separate ISM half band. For more information about setting the dip switches, refer to Installing the Base Station on page 21. If other devices operating on the ISM band interfere with the T7406 base, the other half of the band may be used to try to minimize interference. In this situation, install only one base station and three handsets per location. Spare Parts You can order spare parts for your T7406 telephone. For more information about spare parts, refer to T7406 Parts Lists on page 17. For more information about accessories, refer to Optional accessories on page 49.

Handset Signal Detection
You can monitor the handset signal strength while moving to different
locations. The antenna/signal strength and battery icons appear on the
handset display.
When you move too far from the base station, the following occurs on
the handset:
the antenna/signal strength icon disappears
message appears
handset produces an intermittent beep
handset may go into scanning mode
If the signal strength is weak, move back into range to stop the handset
display messages and warning tones.
If you go completely out of range during an active call, the call is
automatically placed on hold. For more information, refer to Hold calls
on page 43. Retrieve a held call by selecting the flashing red line button
when you are back in range.
Note:In cases where the line button does not light when you move back
into range of the base station, press the intercom/line button that
the call came in on, to take the call off hold.
