[. . . ] The desk set is always in receive mode unless the user presses the TRANSMIT or IC buttons. The desk set contains an internal or local speaker and a handset speaker, which operate as follows: · · When the handset is in the cradle, or on-hook, receive audio is heard on the local internal speaker. When the handset is off-hook, receive audio is routed to the handset. Handset Transmit Using the handset is recommended when the desk set is located in noisy surroundings. Press the handset PTT bar or TRANSMIT button and speak into the handset microphone. Transmit From Internal Microphone Use the internal microphone only in low noise environments. The handset must be on-hook for the internal microphone to operate. Press the TRANSMIT button and speak in the direction of the internal microphone. For the best transmit audio quality, maintain a distance of about 12 to 18 inches from the microphone. 11/10 10 Installation Planning the Installation Sample IDR1000A Installation Diagram 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 IDR1000A DC Remote Desk Set Use and Installation Manual 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 I circuits by at least 2 inches. The exception is where Class I 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 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. The IDR1000A DC 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 with the same type Bussmann C515S-1. 25 A fuse. 11/10 12 IDR1000A DC Remote Desk Set User and Installation Manual Installation Power Connections Power is supplied to the desk set from a listed ac adapter. Make connections to the main circuit board according to the following table: TS1 Pin # Function 1 2 3 4 5 6 N/C N/C Line Signal Connection (­) Line Signal Connection (+) Ground and dc minus or (­) Power (+)10. 5 to 16 V dc (lead with white dashed line) 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 2-wire line to the terminal block position on the main circuit board labeled LINE 1. 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. [. . . ] Check for a blown fuse and ensure that the desk set is connected to a dc power source. The desk set will not cause the dc remote adapter to key the radio. Ensure that the proper dc current magnitude for the dc adapter to key the radio is programmed into the desk set. Ensure that the desk set's output level is set properly, and that the DCLOTL is set in a range of 5 mA to 14 mA into the telephone line. RX audio is low or distorted. Ensure that the dc 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. [. . . ]
