Figure 3-1) Appearance of PX-Series Radio Figure 3-2) Top Appearance of PX-Series Radio 3.2 Basic Operation Method Please read this user guide carefully before using this PX-Series Radio. This user guide contains the detailed explanation about the installation & removal method of antenna and battery. 1) Installation and Removal of Antenna The Figure 3-10 shows the installation and removal method of antenna.
Figure 3-3) Installation & Removal method of Antenna 2) Installation and Removal of Battery The Figure 3-1 shows how to remove battery. The material of Radio body on which the battery is installed is aluminium. If pushing the battery softly after alignment (③) of battery on the Radio body in aluminium material, the battery is installed with a similar sound to camera shutter.
Figure 3-4) Installation & Removal method of Battery 3) How to Disassemble Radio Unscrew 2 screws at the back side of Radio as shown on Figure 3-3 and by using a jig, pull the jig to the (O) direction and give the jig a lift to the (X) direction. Then, the case is disassembled from the Radio.
4) Components of PX-Series Radio PX-Series Radio CHX-150FB PBX-2150LA User Guide Hand-Strap Antenna 4. How to charge the Battery 4.1 How to charge the Battery PX-Series Radio is designed to use 2 kinds of batteries, which are PBX-2150LA (1500mAH Li-ion) of standard type. The PX-Series Radio receives power from high-performance Li-ion battery. The battery is safe, of high-performance and highly reliable.
4.2 When to charge Battery Low battery voltage will shorten the talk range and will make the performance of Radio worse. Please make charge in case of followings. 1) When the battery has low performance after being used for 10~12hours 2) When the red LED on the front of Radio blinks (every 0.5 second) during transmitting or receiving signal 3) When a “beep“ sound (alert sound indicating low battery) is generated while the Radio is in use 4.2.
4.4 Charger (CHX-150FB) The CHX-150FB charger is designed to charge only the Li-ion battery enclosed in this Radio. It is possible to use the AC input voltage of AC85~250V.
5. Operating Instructions of PX-Series Radio 5.1 Power On/Off Turn Power switch clockwise and as soon as power is supplied, a “beep” sound is heard or the “Star Spangled Banner” is played and the Radio enters into the previous latest state. ☞ Caution : If turning power on by pressing a button on Radio, the Radio may enter into a special mode and in this case, the transmission and reception of Radio may not be possible. Don’t use the Radio for the other purpose apart from the above. 5.
5.5 Adjusting Transmission Power The transmission power can be changed to High-Power or Low-Power. If pressing the MENU (SCAN) key during pressing the PTT Key, the red LED (High-Power) is turned on and if pressing the MON key, the yellow LED (Low-Power) is turned on. By changing the power to Low power under a good communication condition, the user can extend the use time of battery. 5.
5.8 Compander Function This function is for improving the quality of voice. When transmitting, it transmits compressed voice and when receiving, it expands the compressed voice, which is for improvement of communication quality. * Selection Method of Compander If turning on power during the PTT + MENU (Scan) key, the conversion sound of Compander Mode is generated and from that time, the Compander function operates. Although the power is turned off and on, the Compander function is maintained.
5.10 Indication Function of Batter Voltage In order to check the remaining battery capacity, press the MENU (Scan) + MON key successively at Normal Mode. Then, the LEDs show the followings for 1 second and return back to the original. -. Green LED is turned on. : satisfaction -. Yellow LED is turned on. : sufficiency -. Red LED is turned on. : Shortage -. Red LED blinks with an alert sound. : Turn-off 5.
5.14 Scramble / Descramble Function This function is used to protect the PX-Series Radio from overhearing of the other Radio which is using the same frequency. If turning on the power during pressing the MENU (Scan) + MON key, the conversion sound to Scramble Mode is generated and at this time, Scramble Function is operated. And although the power is turned off and on, this function is maintained.
