REN, Freestyle 500 has a REN of 1.

Freestyle 500 is designed for residential or normal office use, they should be installed away from sources of direct heat, excessive humidity, dust and vibration.

Approximate overall dimensions are:

Remote charger unit with cordless handset on rest: 150mm x 230mm x 90mm
Telephone base unit with corded handset on rest: 160mm x 220mm x 85mm
Weight of packaged instrument 1.8Kg.

A phone socket and 240 Volt, 13 Amp mains socket are required within 3 Metres of the base unit, mains power consumption is approximately 5 Watts.
A mains socket is also required within 3 metres of the remote charger unit.

For maximum radio range the base unit wire antenna should be fully extended. The base unit should also be mounted away from any sources of Radio Frequency Interference or structures which may affect radio signals. In domestic premises locating the base unit in an upstairs room will give better range than at ground level. The telescopic antenna of the cordless handset should be fully extended during use for optimum range.

Under trial conditions no problems were encountered with Freestyle 500 when connected to any small, medium or large PABXS. If problems occur in the field, a 1.7 Mhz Medium Wave RF filter (e.g. Plug in RF filter Item Code 877596) may need to be connected between the cordless telephone and the PBX/KTS.

NOTE: Fitting of these filters does not guarantee compatible working. Should problems persist, the customer should be informed that it is inadvisable to use this product with the associated PBX.

Cordless telephones can be affected by interference. e.g. from fluorescent lights or electrical appliances and range can be reduced by the screening effects of building structures, e.g. steel framework, foil backed wallboards.

There are 8 pairs of frequencies allocated for CT 1 cordless telephony use, interference or overhearing may occur where other cordless telephones on the same or adjacent channels are located nearby. In such cases Freestyle 500 should be selected to have the greatest (at least two) channel difference from any other nearby CT1 cordless telephones.

Freestyle 500 is intended for retail sale and customer installation only.
Installation instructions are included in the product user guide and involve siting the base unit within reach of a phone socket and mains socket where it will give maximum range.

Setting the channel switch (A or B. Base unit and cordless handset to similar setting).

Setting mode switch on base unit (E for Earth recall PBXs or TB for Timed Break recall PBXs or for Network Services on DELs).

Although the cordless handset batteries may have enough power to make a simple functional test, the cordless handset batteries should be charged for 24 hours before full use.

Maintenance on rental Freestyle 500s only, is limited to functional testing (following the Help section in the User guide, supplied with the instrument). Checking the mains transformer and charging unit are functioning and that the facility switches are set correctly. If any part of the Freestyle 500, excluding aerial, transformer or cordless handset battery, is found to be faulty, the unit should be changed.

Security codes
Freestyle 500 handsets and base units are matched together by their security code signal 'handshake'. The security coding prevents unauthorised access to the line by other cordless telephone users, the handshake is repeated at approximately ten second intervals during calls to ensure that only the matched handset controls the call. There are over 65,000 security codes, these are fixed on manufacture hence cordless handsets and base units should be regarded as 'matched pairs' and not separated, additional or replacement handsets are not available.

Use on PBXs and Key Telephone Systems (with 2-wire ports).
Freestyle 500 is approved for use as extensions to switching systems (PBXs approval in categories 1,3,5,7,9 & 11).
As with other CT1 cordless telephones, some of the 1.7MHz signal from the base unit may be picked up by the switching system causing system misoperation.
No problems have been found when used on Medium & Large PBXS.

Incoming ringing signal.
To comply with user safety requirements for prevention of acoustic shock, the cordless handset tone caller output is regulated and builds up in volume over 4 bursts of ringing. Freestyle 500 has been designed to cadence-follow when ringing.

Radio power output.
To comply with CT1 requirements, the effective radiated power (ERP) transmitted by the cordless handset or base unit must not exceed 10 milliwatts, the Base unit transmits 1.7Mhz signals from the wire aerial to the ferrite aerial inside the cordless handset and the handset transmits 47Mhz signals from the telescopic aerial to the base unit wire aerial.

Calls on any CT1 telephones are not secure from overhearing and may be picked up by other cordless telephones operating on the same frequencies or by Medium Wave radio receivers, Freestyle 500 will cleardown cordless handset calls if the 'handshake' is affected by an interfering call.

Intercom regulations.
Intercom call duration is limited by regulations. A warning bleep will be heard 30 Seconds before an Intercom call is automatically cut off at 2 Mins and 50 Secs. If an intercom call is timed out, further intercom calls may not be made until 60 seconds has elapsed. Intercom calls not following timed out calls may be made immediately.

Cordless handset battery charging.
Freestyle 500 requires 24 hours for a full charge, fully charged batteries should, in practice, give 12 hours use in talk mode 30 Hours in standby Mode. If the batteries need recharging, the cordless handset will emit a warning tone and BATT will be displayed on the LCD. This occurs in either talk or standby mode. Users are recommended to leave the handset on charge over night in normal use. Battery capacity can be expected to reduce after 2 years use when customers can have new batteries fitted in the handset at BT Phoneshops for a charge. If customers wish they can fit the batteries themselves. Rental customers will have the handset battery replaced free of charge.
