User manual YAESU VX-2500

[. . . ] This radio is restricted to occupational use, work related operations only where the radio operator must have the knowledge to control the exposure conditions of its passengers and bystanders by maintaining the minimum separation distance shown below. Failure to observe these restrictions will result in exceeding the FCC RF exposure limits. Antenna Installation: For rear deck trunk installation, the antenna must be located at least the following distance away from rear-seat passengers in order to comply with the FCC RF exposure requirements. [. . . ] If you want to select an operating group from a different system, press the [s]/[r] button to select the system you want before selecting the operating group. Setting the Volume r Turn the VOL/PWR knob clockwise to increase the volume, and counterclockwise to decrease it. Transmitting CONVENTIONAL SYSTEM r In conventional mode, monitor the channel and make sure it is clear. Press the PF button which is programmed to the Monitor feature to listen for channel activity. While holding in the PTT switch, speak across the face of the microphone in a clear and normal voice. For best transmission, hold the microphone about 1-1/2 to 2 inches away from your mouth. If the Busy Channel Lockout feature has been programmed on a channel, the radio will not transmit when a carrier is present. Instead, the radio will generate a continuous low-pitched tone while the PTT switch is pressed. Release the PTT switch and wait for the channel to be clear of activity. r r r r VX-2500 OPERATING MANUAL Page 5 BASIC OPERATION OF THE TRANSCEIVER r If CTCSS or Digital Coded Squelch (DCS) Lockout has been programmed on a channel, the radio can transmit only when there is no carrier being received or when the carrier being received includes the correct CTCSS tone or DCS code. TRUNKING SYSTEM r Press the PTT switch. While holding in the PTT switch, speak across the face of the microphone in a clear and normal voice. For best transmission, hold the microphone about 1-1/2 to 2 inches away from your mouth. r If all channels are busy, a continuous tone will be heard from the radio, and the " " icon will appear on the LCD when the PTT switch is pressed. r If the radio is out of range during the transmitting attempt, slow beeps will be heard followed by a continuous tone from the radio. Automatic Time-Out Timer If the selected channel has been programmed for automatic time-out, you must limit the length of each transmission. Another beep will sound just before the deadline; the " " indicator will disappear and transmission will cease soon thereafter. To resume transmitting, you must release the PTT switch and wait for the "penalty timer" to expire (if you press the PTT switch before this timer expires, the timer restarts, and you will have to wait another "penalty" period) Page 6 VX-2500 OPERATING MANUAL ADVANCED OPERATION Programmable Function (PF) Buttons The VX-2500 includes nine Programmable Function (PF) Buttons. The PF button functions can be customized, via programming by your VERTEX STANDARD dealer, to meet your communications/network requirements. Some features may require the purchase and installation of optional internal accessories. The possible PF button programming features are illustrated below, and these functions are explained on the pages to follow. [. . . ] During ARTS operation, your radio automatically transmits for about 1 second every 25 seconds (the interval is programmed by the Dealer) in an attempt to shake hands with the other station. If you move out of range for more than two minutes, your radio senses that no signal has been received; a ringing beeper will sound, and "OUT OF SERVICE" will scroll on the LCD. If you subsequently move back into range, as soon as the other station transmits, your beeper will sound, and "IN SERVICE" will scroll on the LCD. DTMF Paging System (Requires the optional FVP-25 Encryption/DTMF Pager Unit) This system allows paging and selective calling, using DTMF tone sequences. [. . . ]
