    With the Model 280, however, the display of each remote can be updated when any remote in the system sends a command to the base station. A Model 280 will show the latest base station frequency as well as other parameters such as intercom and privacy.

  • Page 8: Digital Audio

    The Model 280 and 284 have the capability to mute all incoming guard and function tones from parallel remotes. A tone detector combined with a momentary audio delay allows for complete tone muting.

  • Page 9: Paging Encoder

    General Paging Encoder The Digital Tone Remote is equipped with a versatile, built-in, paging encoder. This provides an easy method of selecting specific field radios and pagers for receiving alerts and voice pages. The encoder supports Two-Tone (both 100- and 1000-call), DTMF (all 16 tone pairs), Five-Tone signaling (EIA, CCIR, ZVEI tone groups), and Pulsed-Tone Dialing.

    Operation Overview This section discusses the normal operations of the remote deskset. It will cover how to operate the controls and the indications that should be observed by the operator as he or she uses the unit. Power Earlier models are powered once the power supply is connected. Later models have a power switch at the back/top of the unit.

Clear The CLEAR button is located on the right hand side of the remote, the top button in the column of three that has the TRANSMIT button in it. This button is primarily used to clear paging entries made from the keypad.
  • Page 19 Paging Keypad The Model 280 and 284 remotes have a 16 button keypad to support paging entries. Pages can be entered in two ways. The operator can enter the capcode of the pager directly on the keypad, or the list of programmed pagers can be stepped through by using the “*”...

  • Page 20: Indicators

    Operation assigned to it or the complete entry is not a valid capcode under the rules for the format in use, then the remote will return an error message and prompt the operator to try again. Paging entries can be canceled or cleared either before or after a page is made by pressing the CLEAR button which is next to the upper right hand corner of the paging keypad.

  • Page 21: Function Tones

    The operator should not hear any control/function tones being sent when he or she operates any control on a Model 280 or 284, since the remote mutes its speaker or headset audio while those tones are being sent. They should not hear any tones from parallel remote equipment in the system either, since the remotes are programmed to recognize the tones from other units and mute its receive audio until they are finished as well.

    Call Decoder The call decoder feature works in conjunction with a Zetron HEAR Decoder and allows field radios to alert a specific remote or group of remotes. This is useful for cases where the remote operators wish to hear only those transmissions intended for themselves and not hear all traffic on the channel.

  • Page 24: Paging Feature

    Operation Paging Feature The number of formats supported, the different ways in which to initiate a page, keyup delay, tone levels, and frequency equalization curves are all organized to allow the end users to operate the remote in the ways that suit their needs rather than reorganizing their operations to suit the remote.
  • Page 25 Note The transmitting of pages can only be accomplished by pressing either the TRANSMIT button in the lower right hand corner of the remote deskset, or the button above it, depending on the system programming. The PTT bar in the handset will not cause a page to be transmitted, even if the handset is off-hook.
  • Page 26 Operation Stack Paging The Digital Tone Remotes support the function of stack paging, that is, paging a number of different users as the result of a single paging entry on the remote. The Digital Tone Remotes can support a total of ten stack pages, and each of these stacks can have up to ten pagers included in them.

    Installation Overview This section contains information and instructions on installing Zetron’s Digital Tone Remotes into either new or existing radio systems. It covers both the physical installation of the unit and the initial setting of audio levels. It does not cover the programming of the remote as far as functions of its programmable buttons or its paging feature.

  • Page 33: Power Connections

    Power Connections The Digital Tone Remotes must be properly grounded. The simplest method for proper grounding is to use Zetron's 13.5VDC switching power supply (P/N 802-0692) in a grounded outlet. This power supply accepts 100VAC to 240VAC, uses an IEC power connector, and is certified in several countries.
