BEFORE Y OU BEGIN Battery Pack Installation and Removal r To install the battery, hold the transceiver with your left hand, so your palm is over the speaker and your thumb is on the top of the belt clip. Carefully mate the battery’s four insertion slots with their corresponding alignment tabs on the transceiver case, while tilting the Belt Clip outward. Proper alignment occurs with the battery pack offset about 1/2 inch from the top edge of the battery compartment.
OPERATION Preliminary Steps Quick Start r Install a charged battery pack onto the transceiver, as described previously. r Screw the supplied antenna onto the Antenna jack. Never attempt to operate this transceiver without an antenna connected. r If you have a Speaker/Microphone, we recommend that it not be connected until you are familiar with the basic operation of the VX-900. r Turn the top panel’s V O L / P W R knob clockwise to turn on the radio on.
OPERATION r Rotate the VOL/PWR knob to set the volume level. If no signal is present, press and hold in the MONITOR button (under the P T T switch) more than 2 seconds; background noise will now be heard, and you may use this to set the VOL/PWR knob for the desired audio level. Press and hold the MONITOR button more than 2 seconds (or press the MONITOR button twice) to quiet the noise and resume normal (quiet) monitoring. r To transmit, press and hold the PTT switch.
OPERATION r Switch the top panel’s TOGGLE switch to the [A], [B], or [Center] position to activate one of the pre-programmed functions which may have been enabled at the time of programming by the dealer. When this switch is in the [A (left)], [B (right)], or [Center] position, the feature programmed (by your dealer) to that switch position will be activated. See the next section for details regarding the available features.
ADVANCED OPERATION Soft key and TOGGLE switch Functions The VX-900 includes the [TOP SEL], [SIDE SEL], [MONITOR], and [LAMP] keys, and the TOGGLE switch, while the 16-key version additionally provides [A], [B], [C], [D] function keys. The Soft key and TOGGLE switch 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.

ADVANCED OPERATION Description of Operating Functions Channel Scan The Scanning feature is used to monitor multiple channels programmed into the transceiver. While scanning, the transceiver will check each channel for the presence of a signal, and will stop on a channel if a signal is present. One key or switch may be assigned to the Scan function, as follows: r One of the Soft keys may be assigned for Scan operation; or r The TOGGLE switch may have one position assigned to the Scan function.
ADVANCED OPERATION Low Power Press the assigned Soft key or switch the TOGGLE switch to the assigned position to set the radio’s transmitter to the “Low Power” mode, thus extending battery life. Press the assigned Soft key again or switch the TOGGLE switch to the other Position to return to “High Power” operation when in difficult terrain.
ADVANCED OPERATION 12 Encryption Disable Press the assigned Soft key or switch the TOGGLE switch to the assigned position to turn off the optional voice encryption unit temporarily, for use when an incorrect setting of (or failure in) the encryption system at one end of the communication path has made it impossible to talk to the other station. Remember that disabling the encryption will mean that your transmissions are no longer secure.
ADVANCED OPERATION pressed the key), you can set up the “Dual Watch” feature by rotating the CH selector knob to another channel. The radio will then scan back and forth between the original User-assigned Priority Channel and the newly-selected channel. The Priority Channel you have assigned (before pressing the key) will be retained in memory until you change it. Channel Group Selection The VX-900 is capable of separating its 512 memory channels into any of 20 Groups.
ADVANCED OPERATION ing the Soft key. To restore a particular channel to your scanning list, press and hold in the Soft key again for one second; “- S T O P - ” will appear on the LCD for one second after pressing the Soft key. Call/Reset This feature, if enabled, allows the user to change the 3-digit Page Call code, used to call other similarly-equipped stations. Press the Dealer-assigned Soft key, followed by the three digits representing the Page Call code of the station you wish to call.
ADVANCED OPERATION ARTS (Auto Range Transpond System) DTMF Paging System This system is designed to inform you when you and another ARTS-equipped station are within communication range. This system allows paging and selective calling, using DTMF tone sequences. 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.
UNDERSTANDING R ADIO WAVES Radio waves travel from one point to another by several different means. The general term for these methods of wave travel is “propagation.” You may know that “shortwave” signals can be propagated over distances of several thousand miles by reflection off of the upper regions of the atmosphere. Your hand-held transceiver, on the other hand, operates on the so-called VHF (Very-High Frequency) or UHF (Ultra-High Frequency) bands.
