which passed the band-pass filter (BPF) consisting of two levels o f LC t o elimi nat e the unne cess ary signals,
then sent to the low noise amplifier (LNA) consisting of Q703 and its peripheral components for
enlargement.
After passing the band-pass filter (BPF) consisting of three levels of LC to further eliminate the
unnecessary out-of-band signals, the output of LNA is then sent to the first frequency mixer (Q702).
• The First Frequency Mixer
The signal from LNA is mixed with the f irst l oca l osci llator signa l fro m the frequ ency sy nthesiz er t o gener at e
the first intermediate-freq uency signal (51.65MHz).
• IF Circuit
The first intermediate-frequency signal eliminates the signals from the adjacent channels or other signals
through the crystal filter. (Z1)
The first intermediate-frequency signal from the crystal filter, after being amplified by the first
intermediate-frequency (IF) amplifier (Q701), is sent to IF processing IC (IC700, GT3136).
IF IC consists of the second frequency mixer, IF amplifier, amplitude limiter, frequency detector, noise
amplifier , audio low pass filter.
The 12.8MHz signal from X300, being amplified by Q300 and its peripheral circuit, becomes the second
local oscillation signal (51.2MHz). The second local oscillation signal (51.2MHz) mixes with the first
intermediate-frequency signal (51.65MHz) in IC700 to generate the second intermediate-frequency signal.
The second intermediate-frequency signal amplified in IC700 with its amplitude being limited, being filtered
by the FD1 ceramic filter (450 kHz ) , is demodulated by IC700 to generate the audio signal.
• Squelch Circuit
The signal demodulated by IC700 is sent to its own noise amplifier for amplification, and the amplified
signal is sent to Q700 for fur ther a mpli ficatio n and to D701 for d etec tion; the pr oduced d irect current is t hen
sent to MCU squelch control circuit, and its voltage is inversely propor t ional to the input signal.

The modulated RF signal from VCO, being ampl ified by Q303、Q304、Q602、Q603、Q601, is sent to Q600
for power amplification.
The grid bias of Q601 and Q600 is controlled by APC (Automatic Power Control) circuit. Change the grid
bias voltage to easily cont r ol the output power strength of the transmitter.
• APC
（Automatic Power Control）Circuit
R620, R621 and R622 are power amplifier current detection, and IC600A is a power amplifier current
sampling amplifier. IC600B is a power comparis on amplifier.
The extra high output power of the transmitter will increase the power amplifier current and IC600A output
with a decrease in IC600B output voltage. It will also decrease the bias voltage on Q601 and Q600, which
decreases the output power of the t ransmitter, and vice versa. This enables the stability of the output power
in different working c ircumstances.
MCU changes the voltage being input to IC600B to set the power.

This radio applies PLL frequency synthesizer.
The frequency synthesizer consists of reference oscillator, voltage controlled oscillator (VCO),
programmable frequency divider, phase comparat or and low pass filter.
Q307, D305, D306, D307, D30 8 and other r esist ance-cap acit ance un its make up the tr ansmitting VCO unit .
D304 is the modulation circuit of the transmitting VCO.
Q302、D300、D301、D302、D303 and other resista nce-cap acita nce units make up the receiv ing VCO unit.
IC300 (MB15E03) is a PLL integrated circuit which contains a programmable reference frequency divider,
programmable frequency divider, phase comparat or and charge pump.
R329, C358, R330, C359, R331, R332 and C360 make up the loop filter.
The reference frequency i s pr ovided by X300 (TCXO, 12.8MHz).
The reference frequency from TCXO (Temperature Controlled Crystal Oscillator） is divided by the
Page 7 of 96
FP560 Ser vi ce Manual
programmable reference frequency divider in IC300 to become the 5kHz or 6.25kHz (controlled by MCU,
according to the setting channe l) r eference frequency .
The oscillation frequency from VCO, being amplified by the two-time frequency multiplier circuit, is sent to
IC300 for comparison with referenc e frequency after being divided by the programmable fre quency divider,
and the error signal is then generated to change the oscillation frequency of VCO after filtered by the low
pass filter. VCO is locked when the frequency of VCO r eac hes a certain set value.
Loss of Lock Detection: When PLL loses its lock, IC300 pin14 outputs the electric level signal to MCU, and
MCU control transmitter forbids transmitting and issues an alert tone. The output voltage of IC300 pin14 is
high electric level when it is locked.

data.
CTCSS/DCS Signal Encoding and Decoding:
The CTCSS/DCS signal gener at ed by MCU is sent separately to VCO and TCXO for modulation.
The CTCSS/DCS signal from the receiver is sent to MCU for decoding. The MCU identifies whether the
CTCSS/DCS signal of the r adio i s t he same as the receiving signal so as to turn on the speaker.
CTCSS
CTCSS (continuous ton e control squ elch sy st em) is a sque lch cont ro l syst em modu lated on the c arr ier w it h
the CTCSS signal being the pilot frequency. If the CTCSS feature is set, the conversation is enabled only
when the CTCSS frequency from the receiver and transmitter is the same to avoid interference from other
signals.
39 groups of standar d CTCSS frequency of this radio are available. See Char t 1.
CTCSS signal is generated by MCU (PW M wave form), and it is sent to VCO for modulation after being
filtered by the low pass fi lter composed of RC for eliminating the frequency higher than 300Hz.

DCS Signaling:
DCS (Digital code squelch) is a continuous numerical code which is modulated along with the speech
signal on the carrier to control the squelch. If the DCS feature is set, the speaker is on only when the same
DCS code is received to avoid the unnecessary signal interference.
83 kinds of standard code of this radio are available. See chart 2.
DCS signal i s generated by MCU (PWM wave form), and it is sent to VCO and TCXO for modulation after
being filtered by the low pass filter composed of RC for eliminating the frequency higher than 300Hz. VCO
modulates the high frequenc y of DCS signal and TCXO modulates the low fr equency of DCS signal.
CTCSS/DCS signal from the receiver is sent to MCU for decoding. MCU identifies whether the receiving
signal has the same DCS code as t he r adio so as to turn on the speaker.

4. Function Description and Parameter Settings
4.1. Time-out Timer
This feature prevents the user from long occupation on the cha nnel. If the transmitting period exceeds the
dealer’s preprogrammed time, the radio stops transmitting and rings alert tone. To stop the alert tone,
please release the PTT button. For a second transmission, please press the PTT button after a certain
period (set by the dealer). If the dealer preprograms the pre-warning feature, a warning is given when the
transmitting period gets close to its time-out-timer limitation, indicating the t r ansmission is forbidden soon.
4.2. Channel Scan
The channel scan is able to search for the channel where there is a signal, and the radio stays on the
channel where a signal is detected for making a conversation. The scanning mode is the carrier control
scan.
4.2.1. Carrier Control Scan
The radio scan stays on a busy channel until it is no longer busy, and the scan is enabled automatically
after a certain peri od ( t he s pecific period time is set by the local dealer).
Press the Scan shortcut key, and the radio scans the scan list of the current channel. When the radio is
scanning, you can press the “ Scan” shortcut key to stop the scanning.
4.2.2. Scan Reply Channel
When the radio is scanning, press the PTT button to transmit and make a conversation on a preset
channel, and the channel is prepr ogrammed by the local dealer.
4.3. Kill and Activation
If the dealer preprograms this feature, the radio can receive and decode other radio’s signals of kill and
activation before responding accor dingly. After bei ng killed, the radio can only receive the activated signal
without being able to transmit or r eceive other signals. The radio is back to normal a fter activation.
Page 15 of 96
FP560 Ser vi ce Manual
4.4. Emergency
In a state of emergency, press the “Emergency On” button (the button is programmed as the “Emergency
On” button) for the alarm call. To disable the emergency feature, please press the “Emergency Off”
shortcut key or restart the radio.
The alarm method is composed of two parts：
• Alarm type: mainly specifies the acoustooptic reaction in the state of alarm call.
• Alarm mode: specifies the content sent in the state of alarm call. You can set these parameters through
the dealer to meet your require m ents.
Alarm Mode:
• None: No alarm feature (by default), and the alarm f eat ur e cannot be enabled by pressing the
emergency button.
• Siren Only: The radio only emits siren lo cally.
• Regular: The acoustooptic alert can be enab led, and the radio is able to receive.
• Secret: No acoustooptic alert and the radio is not able to receive.
• Secret but receivable: No acoustooptic alert but t he r adio is able to receive.
Alarm Mode:
• Emergency Alarm: After the alarm feature is enabled, the radio only transmits an emergency alert , and
afterwards, then auto m at ic exit the alarm status.
• Emergency Alarm + Emergent Call: The radio transmits an emer gency alarm and sends out an
emergency call by pressing t he PTT button.
• Emergency Alarm + Auto Transmission of Background Tone: The radio transmits an emergency alarm,
and the background tone will be sent out periodically and automatically in the way of emergency call.
Note:
• Emergency Alarm: A non-speech signal transmitted by t he r adio to inform other radios to send out an
alert.
• Emergency Call: A call mode in the priority of using the channel to ensure a successful call during
emergency.
4.5. Parameter Settings
The radio is preset before the factory delivery, but the parameter of the digital feature, operational
frequency, channel, QT/DQT, and auto scan feature may be reset according to different requirements of
the customers. Hence, Kirisun designed a Chinese/English FP520 programming software with friendly
