PERSONAL SAFETY
SAFETY PRECAUTIONS
These Safety Precautions, Warnings and Cautions advise personnel of specific hazards which
may be encountered when using this equipment and that control measures may be required to
prevent injury to personnel, and damage to equipment and/or the environment.
Before using this equipment, users are to acquaint themselves with all risk assessments relevant
to the equipment and area of use. Users must comply with the control measures detailed in the
risk assessments.
References covering safety regulations, health hazards and hazardous substances are detailed
under the WARNINGS section below. These are referred to in this user manual when they are
encountered.
GENERAL SAFETY PRECAUTIONS
Do NOT operate your portable radio without a hands-free kit while driving a vehicle (subject to
local law).
Do NOT operate your radio in areas that contain hazardous material – unless the radio’s level of
IECEx approval is approved for use in that area.
Obey the ‘Turn Off Two-way Radios’ signs where they are posted, e.g. in a fueling station.
Do NOT touch the antenna while the radio is transmitting.
Do NOT dispose of batteries in a fire.
Dispose of batteries according to local recycling regulations. Do not dispose as household waste.
Do NOT attempt to disassemble the battery.
When charging a battery, keep it at a temperature between 41°F ~ 104°F (5°C ~ 40°C) to ensure
a full charge. Temperatures outside this range significantly reduce battery life. The operating time
(talk-time and standby time) is noticeably shorter than normal, replace the battery.
Before charging a battery attached to a radio, turn the radio off to ensure a full charge. Never
leave a radio on while in the charger, as it can damage both the battery and the radio; the
charger is not a radio stand.
Do NOT cut off the power supply or remove battery while charging.
Do NOT charge a battery that is wet. Dry it with soft cloth prior charging.
The battery will eventually weaken. When the operating time (talk-time and standby time)
becomes noticeably shorter than normal, replace the battery.

Battery performance greatly decreases at temperatures below -4°F (-20°C). Having a spare
battery is always necessary in extremely cold environments. A cold battery may work again when
it returns to room temperature, so keep it for later use.
Dust on the battery contact may cause the battery not to work or charge properly. Use a clean
dry cloth to wipe it before attaching the battery to the radio.
Batteries with damaged contacts can be extremely dangerous. Any battery with damage to one
or more contacts should be replaced immediately and not used under any circumstances.
Do NOT operate the radio if the antenna has become disconnected or damaged. Recharge
batteries only in an approved battery charger.

RPX4500/RPX4600 P25 PORTABLE RADIO – USER MANUAL 17
4. MENU SYSTEM
Your RPX4600 P25 portable radio uses a programmed menu structure to access all the radio
features and functions. The structure of the menu can be configured using the PS to meet your
specific needs.
Normally the menus are divided into two menu lists, which are the Main menu list and the Setup
menu list. Menu selections that are not frequently accessed are normally put under the Setup
menu list.
The menu structure of the radio is illustrated in Figure 4.
Possible Menu entries are:
• Zone (usually the first menu as it is often accessed). • Radio Info.
• Squelch. • Mode.
• Mute Adjust (FM)/Monitor (Digital). • RSSI.
• Phonebook. • Crypto.
• Phonebook Edit. • Stored Calls.
• User Options. • Messages.
• Setup. • Scan Edit.
• Contrast. • Phone Call.
• Alert Volume. • Status
• Location Report. • Undefined (No Menu Entry).
The presence and order of the above menu selections is determined by your PS configuration.
The Setup menu is a special case entry. Setup is a subgroup that can have any of the menu
selections assigned to it. This means that less frequently used selections can be partly hidden
away under the Setup subgroup but still remain accessible.
The order and presence of the Setup subgroup selections is determined by your PS. For instance
Info, RSSI and Contrast could be placed under the Setup Menu.
The User Options menu group is also a menu subgroup. This subgroup usually contains on/off
functions, such as Key Beeps or Backlight.
To assist the user in menu key selection, a soft menu label will often appear above the function
keys. The label shows the user the current function for that key, which may change between
different menus.
Programming of menus is a configuration task normally performed by the system manager using
the PS software.

4.1. MENU NAVIGATION
The M key is generally used to select Menu mode from the main Channel Screen. Once in Menu
mode, the / keys cycle through the menus.
To exit Menu mode, press the M key again or the Menu timeout will exit automatically. Generally,
pressing the M key while in a menu will navigate back to the next highest level of menu and the
OK key selects the function.
The / keys are generally used to navigate through a list of options, such as channels, or to
increase or decrease a value.
When the Menu key is first pressed, the numeric keys become short cut keys to functions.
Numeric keys can be programmed with functions using the PS, i.e. Scan.
To access these functions, you can press the ‘M’ or menu key from the channel screen and then
the numeric key assigned to that function.

5. MENU SCREENS
The menu structure on the RPX4600 is configurable using the PS. In most cases, your
system administrator will set up the order and presence of the menu options to your specific
requirements.
This section describes all the menus that are currently available. It also describes the Channel
Screen which is the main default screen that is displayed after the radio is switched on.
Normally, the menus are divided into two menu lists - the Main Menu list and the Setup Menu
list.
In the default configuration, the Main Menu contains the Channel, Zone and Setup menus. This
allows access to the second ‘Setup’ menu level.
The Main Menu can be accessed from the default screen by selecting the ‘M’ (F1) button.
To access any of the menu options from the Main, Setup or User Options Menus, use the and
keys to scroll through the menu options and then press the ‘OK’ button when the required
menu is displayed.
Pressing the ‘Back’ key at any point will go back to the previous screen.
5.1. CHANNEL SCREEN
The Channel Screen shows the current channel and allows channel selection.Pressing the ‘M’ key
enters the Menu mode.
Radio channels may be configured
with the PS as specific frequencies
or as auto-scan types. When an
auto-scan channel is selected, it will
immediately go into scan mode.
Selecting another non-auto-scan
channel will stop the scan.
If a radio channel is defined as a P25
Conventional Digital Channel, it will
only receive P25 digital signals.
If a radio channel is defined as an
Analog FM channel, it will receive both
P25 Digital and Analog FM signals.
Note.
When an Analog FM channel is selected and in Monitor mode, all unencrypted digital
P25 traffic will be heard regardless of NAC or Talk Group.
