DOCUMENTATION User Guide TPU 1881 Phone in card TPU 1881A Product Manual PDM/TPM/A010 PLANNING A Phone Socket and a 240 volts, 13 amp, 50 Hertz mains supply socket are required within easy reach of the instrument. Transformer lead and Line Cord both measure 300Omm. Suitable for use on Phone Socket installations on DELs and most types of 2-wire PBX extensions. Ringer Equivalence Number (REN) is 1. INSTALLATION/COMMISSIONING The User Guide supplied gives sufficient information to install and commission machines at phone socket installations. MAINTENANCE The instrument does not contain any on-site serviceable parts, therefore maintenance is limited to functional testing, checking the facility switches are set to provide optimum performance of the instrument to match the line to which it is connected, the condition of the tape and that the tape head is clean. If the machine fails completely, the output voltage of the Transformer should be checked. The Transformer output is marked 9.5 volts dc, but will measure about 13 volts when tested with the output open circuit. ROUTINE MAINTENANCE The User Guide recommends that the customer should perform the following routines; Every three months, turn the tape over and re-record the announcement. Every six months, clean the tape head, capstan and pinch wheel using a cotton bud moistened with a proprietary tape head cleaning fluid. If the tape is worn, it may be replaced with any high quality "normal bias" MC60 size Microcassette. Although available, longer and shorter tapes must not be used as they will prevent the instrument from operating correctly. The duration between the above routines should be reduced if the machine is heavily used. REMOTE ACCESS Response 300 may be accessed remotely from any Touchtone telephone or by the use of a remote controller. Accessing messages: Call the Response 300 and wait until it answers the call. During or after the announcement,- operate the # key on the telephone or controller. Two beeps will be heard. From the keypad, enter the first digit of the security code, Response 300 will beep once. Enter the second digit of the security code, Response 300 will beep twice. With the correct code entered Response 300 will announce the number of messages received and announce "please wait" while it winds to the correct position on the tape. Should an incorrect code be entered, a second attempt may be made, if this is incorrect, Response 300 will hang up. Memos and messages will be replayed automatically. Message replay will pause every 2.5 minutes and a pause tone will be heard for several seconds. During remote access, keying digits from the keypad or remote controller will allow the user to control the functions of the Response 300. See the user guide for a full explanation of the facilities. Unless messages and memos are reset remotely, they will be saved automatically. WARRANTY New units carry a 21 months warranty from the date of manufacture as shown on the year and week marking on the base of the instrument. These markings form the first 4 digits of the serial number. BT guarantee sold machines (excluding cassette tape) for 12 months from the date of purchase irrespective of the date of manufacture.
