Function Introduction 6.1 Power on/off Power on the radio by long-pressing the power button when it is off. Press and hold the power button for 2 seconds to turn off the radio when it is on. High voltage alarm: If the supply voltage exceeds 16V, the radio will emit a high-voltage alert tone, display “DCH” on the LCD, and disable transmission. Low voltage alarm: If the supply voltage drops below 10V, the radio will emit a low-voltage alert tone and display “DCL” on the LCD. Low voltage auto power-off: If the supply voltage drops below 9V, the radio will power off automatically. 6.2 Channel Selection Users can select the current working channel using the △/▽ buttons on the hand microphone, or directly enter the channel number via the numeric keypad and press the # key to quickly switch channels.(Example: Enter 05 and press #, the radio will switch to Channel 5.) 6.3 Volume Adjustment Users can increase or decrease the radio's receive volume using the VOL+ / VOL- buttons on the hand 7 microphone.The unit supports a total of 10 volume levels from 0 to 9. 6.4 Transmit & Receive To communicate between two radios, both must be set to the same frequency and CTC/DCS code. To make a call, press and hold the PTT button on the microphone and speak into it in a normal voice. Note: For best clarity, hold the microphone 2 to 3 inches from your mouth while speaking. The T icon will appear continuously on the LCD during transmission.The R icon will appear continuously on the LCD during reception. 6.5 Squelch Level Adjustment Users can adjust the squelch sensitivity level via the menu.This radio provides 10 squelch levels (0–9). 0 – Squelch open 1 – Maximum sensitivity (minimum squelch) 5 – Medium sensitivity (medium squelch) 9 – Minimum sensitivity (maximum squelch) 6.6 CTCSS/DCS Settings Users can set the sub-audible tones of the radio via the menu.This radio provides 38 groups of analog tones (CTCSS) and 208 groups of digital tones (104 groups of DCSN + 104 groups of DCSI).Refer to the bottom of this manual for the sub-audible tone frequency list. 6.7 Power Level Setting The radio offers two power levels, high and low, for users to choose from.Users can select different power levels according to different scenarios. Note: Channels 1–7 are set to low power by default and cannot be changed. 6.8 Priority Channel - Set / Recall / Watch To allow users to quickly switch to frequently used channels, this radio provides priority channel setting and recall functions.

SAIN3 LLC 36 Berkley Drive Newark, DE 19702 United States Date: 2026-05-25 Declaration Letter FEDERAL COMMUNICATIONS COMMISSION Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 Subject: Declaration of compliance to the requirements of §15.121 FCC ID: 2AN62-UB15G Dear Sir/Madam, We declare that, this scanning receiver is incapable of operating (tuning), or readily being altered by the users to operate, within the frequency bands allocated to the Cellular Radiotelephone Service in part 22 of this chapter (cellular telephone bands). This device will not be able to receive transmissions in the cellular telephone bands by means of clipping the leads of, or installing, a simple component such as a diode, resistor or jumper wire; replacing a plug-in semiconductor chip; or programming a semiconductor chip using special access codes or an external device, such as a personal computer. This device is also incapable of converting digital cellular communication transmissions to analog voice audio. This device is designed so that the tuning, control and filtering circuitry is inaccessible. Any attempts to modify the equipment to receive transmissions from the Cellular Radiotelephone Service will render the receiver inoperable. This scanning receiver rejects any signals from the Cellular Radiotelephone Service frequency bands that are 38 dB or lower based upon a 12 dB SINAD measurement. We are aware that the modification of this device to receive transmissions from Cellular Radiotelephone Service frequency bands will be considered to constitute manufacture of such equipment. This includes any individual, individuals, entity or organization that modifies one or more scanners. Any modification to receive transmissions from the Cellular Radiotelephone Service frequency bands voids the certification of the scanning receiver, regardless of the date of manufacture of the original unit. Sincerely Yours, Signature: ___________________________ Name: Damon Cheng Title: President

FCC ID: 2AN62-UB15G Page 1 of 2 Radio Frequency Exposure Limit Table 1 to §CFR Title 47 FCC Part 1.1310(e)(1) sets forth limits for Maximum Permissible Exposure (MPE) to radiofrequency electromagnetic fields. Table 1 to § 1.1310(e)(1)—Limits for Maximum Permissible Exposure (MPE) Frequency range (MHz) Electric field strength (V/m) Magnetic field strength (A/m) Power density (mW/cm 2 ) Averaging time (minutes) (i) Limits for Occupational/Controlled Exposure 0.3-3.0 614 1.63 *(100) ≤6 3.0-30 1842/f 4.89/f *(900/f 2 ) <6 30-300 61.4 0.163 1.0 <6 300-1,500 f/300 <6 1,500-100,000 5 <6 (ii) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *(100) <30 1.34-30 824/f 2.19/f *(180/f 2 ) <30 30-300 27.5 0.073 0.2 <30 300-1,500 f/1500 <30 1,500-100,000 1.0 <30 f = frequency in MHz. * = Plane-wave equivalent power density. (2) Occupational/controlled exposure limits apply in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. The phrase fully aware in the context of applying these exposure limits means that an exposed person has received written and/or verbal information fully explaining the potential for RF exposure resulting from his or her employment. With the exception of transient persons, this phrase also means that an exposed person has received appropriate training regarding work practices relating to controlling or mitigating his or her exposure. In situations when an untrained person is transient through a location where occupational/controlled limits apply, he or she must be made aware of the potential for exposure and be supervised by trained personnel pursuant to § 1.1307(b)(2) of this part where use of time averaging is required to ensure compliance with the general population exposure limit. The phrase exercise control means that an exposed person is allowed and also knows how to reduce or avoid exposure by administrative or engineering work practices, such as use of personal protective equipment or time averaging of exposure. (3) General population/uncontrolled exposure limits apply in situations in which the general public may be exposed, or in which persons who are exposed as a consequence of their employment may not be fully aware of the potential for exposure or cannot exercise control over their exposure. For example, RF sources intended for consumer use shall be subject to the limits for general population/uncontrolled exposure in this section.
