Proposed Label Location on EUT FCC ID Label Location

16 October 2007 Equipment Authorization Division Office of Engineering and Technology Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 Ref: FCC ID: UTLF6 Dear Sirs: UNIER TECHNOLOGY CO., LTD. requests acceptance of the labeling proposal described below for transceivers bearing FCC identifier UTLF6. The subject transceivers are compact handheld models as shown in figure 1, authorized under 47CFR Part 80 for maritime services. Figure 1 Because the majority of the transceiver housing is composed of display, speaker, operating controls, and a removable battery pack, there is extremely limited space available to attach the required label carrying the FCC identifier. Attaching the label to the battery pack is not acceptable because the battery pack is a removable item. For this reason, UNIER TECHNOLOGY CO., LTD. proposes placing the label carrying the FCC identifier inside the battery compartment as shown in figure 2. Figure 2 The consumer packaging for these models includes the battery pack as a separate item, NOT installed on the radio. As such, the FCC identifier will be readily visible to the user before the battery pack is installed and whenever the battery pack is removed or replaced. In this location, the label will also be protected from physical abuse and remain readable for the anticipated life of the device. The consumer packaging for these models is a "gift box" which does not allow the transceiver to be seen at time of purchase. In order to meet the requirements of 47CFR Part 2.925 (d), UNIER TECHNOLOGY CO., LTD. will add the FCC identifier " UTLF6" to the outside of the consumer "gift box" packaging. Sincerely,

CIRCUIT DESCRIPTION 1. Frequency Configuration The receiver utilizes double conversion. The first IF is 38.85MHz and the second IF is 450 kHz. The first local oscillator signal is supplied from the PLL circuit. The PLL circuit in the transmitter generates the necessary frequencies. Fig. 1 shows the frequencies.

These BPFs are adjusted by variable capacitors (TC4 and TC5). The input voltage to the variable capacitor is regulated by voltage output from the microprocessor (IC7). 2) First Mixer The signal from the front end is mixed with the first local oscillator signal generated in the PLL circuit by Q19 to produce a first IF frequency of 38.85 MHz.The resulting signal passes through the XF1,XF2 MCF to cut the adjacent spurious and provide the Opitimun characteristics, such as adjacent frequency selectivity CIRCUIT DESCRIPTION 3) IF Amplifier Circuit The first IF signal is passed through a four-pole monolithic crystal filter (XF1,XF2) to remove the adjacent channel signal. The filtered first IF signal is amplified by the first IF amplifier (Q18) and then applied to the lF system IC (IC4). The IF system IC provides a second mixer, second local oscillator, limiting amplifier, quadrature detector and RSSI (Received Signal Strength Indicator). The second mixer mixes the first IF signal with the 38.4MHz of the second local oscillator output (TCXO X3) and produces the second IF signal of 450kHz.The second IF signal is passed through the ceramic filter (CF200) to remove the adjacent channel signal. The filtered second IF signal is amplified by the limiting amplifier and demodulated by the quadrature detector with the ceramic discriminator (CD1). The demodulated signal is routed to the audio circuit. 4) Wide/Narrow Switching Circuit Narrow and Wide settings can be made for each channel by switching the demodulation level.The WIDE (low level) and NARROW (high level) data is output from IC7, pin 6.When a WIDE (low level) data is received, Q301 turn on. When a NARROW (high level) data is received, Q301 turn off. Q301 turns on/off with the Wide/Narrow data and the IC300 detector output level is switched to maintain a constant output level during wide or narrow signals. 5) Audio Amplifier Circuit The demodulated signal from IC4 goes to AF amplifier through IC301.The signal then goes through an AF volume control , and is routed to an audio power amplifier (IC5) where it is amplified and output to the speaker. 6) Squelch Part of the AF signal from the IC enters the FM IC (IC4) again, and the noise component is amplified and rectified by a filter and an amplifier to produce a DC voltage corresponding to the noise level.The DC signal from the FM IC goes to the analog port of the microprocessor (IC7). IC405 determines whether to output sounds from the speaker by checking whether the input voltage is higher or lower than the preset value. To output sounds from the speaker, IC7 sends a high signal to the SP MUTE line and turns IC302 on through Q39,Q23,Q22,andQ38 . (See Fig. 3) 7) Receive Signalling (1) QT/DQT The output signal from FM IC(IC4) enters the microprocessor(IC7) through IC300. IC7 determines whether the QT or DQT matches the preset value, and controls the SP MUTE and the speaker output sounds according to the squelch results. 2) MSK (Fleet Sync) The MSK input signal from the FM IC goes to pin 10 of IC 300. The signal is demodulated by MSK demodulator in IC 300. The demodulated data goes to the CPU for processing. (3) DTMF The DTMF input signal from the FM IC (IC4) goes to IC300. The decoded information is then processed by the CPU.

PLL Frequency Synthesizer The PLL circuit generates the first local oscillator signal for reception and the RF signal for transmission. 1) PLL The frequency step of the PLL circuit is 2.5, 5, 6.25 or7.5kHz. A 12.8MHz reference oscillator signal is divided at IC1 by a fixed counter to produce an oscillator (VCO) output signal which is buffer amplified by Q2 then divided in IC1 by a programmable counter. The divided signal is compared in phase with the 5 or 6.25kHz reference signal from the phase comparator in IC1. The output signal from the phase comparator is filtered through a low-pass filter and passed to the VCO to control the oscillator frequency. (See Fig. 4) 2) VCO The operating frequency is generated by Q4 in transmit mode and Q3 in receive mode. The oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase comparator, to the varactor diodes (D2 and D4 in transmit mode and D1 and D3 in receive mode). The RX pin is set high in receive mode causing Q7 turn on.The TX pin is set high in transmit mode. The outputs from Q3 and Q4 are amplified by Q6,Q100 and sent to the RF amplifiers.
