What causes abnormal programming in Kirisun Portable Radio?
If you are experiencing abnormal programming with your Kirisun Portable Radio, consider the following: * Make sure the wires are well connected. * There may be abnormal output of the RS-232 serial port of the computer, so check the computer. * There may be an abnormal connection of MIC and SPK jack, so check the jack.
Why does my Kirisun Portable Radio phase locked loop unlocked?
If the phase locked loop is unlocked on your Kirisun Portable Radio, it could be due to these reasons: * The phase locked loop crystal oscillator X1 may be broken, so replace it. * The oscillator tube may be broken, so replace it. * The phase locked loop IC2 may be broken, so replace the IC.
What to do if my Kirisun Portable Radio receiving green light is on, but no voice is heard?
If the receiving green light is on but you hear no voice on your Kirisun Portable Radio, check these: * The speaker might be broken. * The audio power amplifier IC9 may be broken, so replace it. * The switch tube Q48 may be broken, so replace it. * The operational amplifier IC6 may be broken, so replace it.
Why does my Kirisun Portable Radio have no signal?
If your Kirisun Portable Radio shows no signal, here are a few things to check: * Make sure the antenna is well connected. * Low sensibility, trimming computer test mode. * The HF amplifier may be broken, so replace it. * The squelch level is too high, which makes the squelch unable to switch on, so reset it by PC. * The mixer tube Q19 may be broken, so replace the tube. * The Frequency Modulation IC4 may be broken, so replace the IC.
What to do if my Kirisun Portable Radio transmitting red light is on, but no voice is heard?
If the transmitting red light is on but no voice is heard on your Kirisun Portable Radio, consider the following: * The power-amplifier tube may have no power output, so replace the tube. * The microphone might be broken. * The operational amplifier IC14 may be broken, so replace it.
Why can't my Kirisun Portable Radio transmit?
Your Kirisun Portable Radio might not be able to transmit due to a few reasons: * The frequencies of both users are not the same. To resolve this, select the same frequency channel again. * The CTCSS/DCS signaling of both users are not the same. To fix this, set it with PC. * You might be beyond the efficient communication range.
What to do if my Kirisun Portable Radio has no display after being switched on?
If your Kirisun Portable Radio's display doesn't turn on after you switch it on, the issue could be due to several reasons: * The battery power may be insufficient, so recharge or replace the battery pack. * The power switch may be broken, consider replacing it. * The CPU may be broken, consider replacing the IC. * The regulator tube Q45 may be broken, consider replacing the IC.
How to fix phase locked loop unlocked with “tick, tick” sound in Kirisun Two-Way Radio?
If you hear a “tick, tick” sound and the phase locked loop is unlocked on your Kirisun Two-Way Radio, the issue could be: * A broken Phase locked loop Crystal Oscillator X1: Replace it. * A broken oscillator tube: Replace it. * A broken Phase locked loop IC2: Replace the IC.
This document outlines the features and operation of the PT6500 two-way radio, a communication device designed for various applications. The manual covers everything from initial setup and basic usage to advanced programmable functions and troubleshooting.
The PT6500 is a two-way radio primarily used for voice communication over designated channels. It supports both individual and group calls, with features designed to enhance communication clarity and security. The device operates on specific frequency bands and can be configured with various signaling options like CTCSS/DCS, DTMF, and 2TONE to filter unwanted calls and ensure privacy within a group. A key function is its Push-To-Talk (PTT) button, which allows users to transmit their voice when pressed and receive signals when released.
The radio incorporates several auxiliary functions that can be programmed via PC software, offering flexibility in its application. These include a Time-out Timer (TOT) to prevent a single user from monopolizing a channel, a Battery Saving mode to extend operational time, and Voice Annunciation of Channel Number for ease of use. The device also supports Busy Channel Lockout (BCL) to prevent interference with other radios using the same channel, and a Scrambler function for enhanced communication privacy.
The PT6500 is designed for straightforward operation, starting with unpacking and checking the supplied accessories, which typically include an antenna, battery, belt clip, charger, power adapter, and hand strap.
The PT6500 offers two side buttons and one top button that can be programmed by the dealer for various auxiliary functions, enhancing user convenience. These functions can be set as short or long key presses.
The manual includes a "Problems and Troubleshooting" section to help users diagnose and resolve common issues. This section provides a list of potential problems, such as "No display after switched on," "Phase locked loop unlocked," "Cannot transmit," "No signal," "Transmitting red light is on, but no voice is heard," "Receiving green light is on, but no voice is heard," and "Abnormal programming." For each problem, a corresponding solution is offered, ranging from simple actions like recharging the battery or checking antenna connections to more complex internal component replacements (e.g., CPU, oscillator tube, amplifier ICs) that would typically require professional service.
The document also emphasizes the importance of using approved accessories, including antennas and batteries, to ensure compliance with FCC RF exposure guidelines and prevent damage to the radio. It advises against disassembling the battery and warns about short-circuiting or exposing it to fire. Regular charging and proper storage are recommended to maintain battery life.
For optimal performance and compliance with RF energy exposure standards, users are instructed to transmit no more than 50% of the time and adhere to specific operating procedures, such as holding the radio one to two inches from the lips during transmission and using approved body-worn accessories. In case of persistent issues or complex repairs, consulting the dealer or an experienced radio/TV technician is recommended.
