The Tecpro wireless system can be used to establish a full duplex wireless conference group of up to 6
personnel.The group can simultaneously talk and listen to all the other users within the same group.
In addition, an un-limited number of listener only belt-packs can be added to the system, useful for personnel
who only need to monitor conversation within the group.
The system operates on a licence exempt UHF frequency of 869.525 MHz and uses encrypted digital
transmission technology for secure communication. It will not interfere with in-ear or radio microphone
systems. Approximate coverage is 300 - 400m depending on the environment.
Major applications are in the theatre, conference, live performance and broadcast markets, though new
applications are constantly emerging.
2.1 Batteries
The batteries are 27-408 Lithium Polymer VARTA EasyPack 3.7V 2600mAh re-chargeable types.
You can re-charge the batteries before they are fully discharged.The batteries are fully re-charged in about
5 hours.
Battery autonomy is about 16 hours. (Average consumption is 200mA - peak consumption is 600mA).
N.B.When stored unused, the batteries keep discharging due to a very small current consumption in the
OFF
mode. Remove the battery from the belt-pack when you stop using it - and check the battery level
before re-using.
Only use VARTA EasyPack 3.7V 2600mAh batteries. Use of any other battery or charger may present a risk of
fire, explosion, leakage, or other hazard. After use, the batteries should be disposed of in an appropriate recy-
cling centre.They should not be disposed of into the environment.
Do not short-circuit the contacts
Do not open the batteries.
Do not expose the batteries to temperatures above 100 deg C.
2.2 Charger
The 27-415 3-way charger is used for re-charging the batteries of the Canford Tecpro TW401 Mk11wireless
belt-pack system. Each charger can simultaneously re-charge up to 3 batteries.This charger must only be used
with VARTA EasyPack Lithium-Polymer, 3.7V re-chargeable batteries.
If the charger is used with any other battery, it could cause that battery to explode.
This charger has been designed for indoor use.The surrounding temperature when re-charging should be
between 5 deg C and 45 deg C. If the temperature is not within this range, re-charging is suspended until the
correct temperature has been reached.
Do not use any other power supply for the charger than the external AC/DC converter unit provided with
the product.The charger should be placed on a flat surface.
