Mounting The desk set can be placed on a desk or mounted vertically on a wall. To wall mount the desk set, remove the four bottom screws from the base and then rotate the base 180°. Reinstall the four screws to the base and rotate the handset hook located on the front of the unit. FCC Interference Warnings The FCC requires that manuals pertaining to Class A and Class B computing devices contain warnings about possible interference with local and residential radio and TV reception. Please read these warnings and all safety information in the Foreword section of this manual. 11 11/10 Installation ITR1000-001 Basic Tone Remote Desk Set Equipment Required Test Equipment · · · · RF service monitor AC voltmeter with dB ranges for measuring audio levels #1 Phillips screwdriver 1/8-inch flat blade screwdriver Documentation · · base station's tone remote adapter manual these installation instructions Cable Installation Safety Considerations Interconnecting, communications, and Class 2 dc power cables should be separated from electrical light or other Class 1 circuits by at least 2 inches. The exception is where Class 1 wiring or power circuits are run in a raceway, or are metal-sheathed or metal-clad, or are permanently separately from the conductors of the other circuitry by a continuous and firmly fixed nonconductor such as porcelain tubes or flexible tubing in addition to the insulation on the wire. Communications cables and in-building wiring should be listed and marked for the purpose according to NEC Article 800. Telephone Line Lightning and Over-voltage Protection The ITR1000-001 Basic Tone Remote Desk Set has an over-current phone line fuse (F2) which protects against occasional extreme fault conditions that may get past the primary protectors. An example of such a fault condition is a power line cross. If the fuse requires replacement, replace F2 only with the same type Bussmann C515S 1. 25A fuse. For maximum surge and lightning protection, building primary (over-voltage) protectors should be installed at the point where the telephone lines enter the radio equipment building. Primary protectors are usually required by local codes and should be provided by your leased line provider. Power Connections Power is applied to the ITR1000-001 from the provided ac wall transformer that is supplied with the unit. Power is applied to TS1-6 (+, lead with white dashed stripe) and TS1-5 (-). 11/10 12 ITR1000-001 Basic Tone Remote Desk Set Installation Line Connections To make the required line connections, a cable with a tinned bare leads stripped to about 3/8-inch or pin terminal is necessary. With the housing opened, route the lines through the slot in the housing bottom. Using a small slotted screwdriver, connect the Line 1 two-wire line to the TS1 terminal block on the main circuit board at terminal positions 3 and 4. Connect the Line 2 two-wire line to the TS1 terminal block at positions 1 and 2. Several desk sets can be connected in parallel. The maximum loss between any two desk sets, or between a desk set and the station, should not exceed 20 dB. Desk sets are shipped with line termination enabled. With parallel units connected, only the farthest desk set unit should be terminated. Setting SWA-6 to off enables line termination; setting SWA-6 to on disables line termination. Refer to "SWA Switch Settings" table in the "Description" section of this manual. Line Considerations - Private Circuit If leased lines from your local telephone company are used between the desk sets and the ITA2000 or similar tone remote adapter, the telephone company (Local Exchange Carrier) may request a Facility Interface Code (FIC). The FIC is subject is to local availability. Analog Facility Interface Code FIC Description 02NO2 2-wire private line; no signaling conversion by LEC (IN-Band) Within a manufacturing plant, a campus, or large building, customer-supplied metallic pairs may be used. It is not necessary to have dc continuity on these lines. Circuit Conditioning The desk set is designed to work with good-quality analog speech band or leased private circuit. [. . . ] Assuming no more than 20 dB of line loss on the telephone line, this level should be adequate for the tone adapter to decode the tone sequence. RX audio is low or distorted. Ensure that the tone remote adapter is wired correctly, including the RX audio pair. Audio quality is limited by the quality of the private radio circuit or leased lines between the station radio equipment and the remote dispatch point(s). In some cases, equalization of the lines or line conditioning may be required to ensure a reasonably flat line. · Too high sensitivity overdrives the unit and results in distorted receive audio.
