Precautions and Maintenance

On battery

• Insert the batteries with the correct polarity.
• Do not mix new and used batteries.
  • The batteries cannot be charged.
• Remove the batteries when the unit will not be used for a long time.
• Should any battery leakage occur, wipe the battery case well and install new batteries.

On placement

• Do not leave the unit in a location near heat sources, or in a place subject to direct sunlight, excessive dust or mechanical shock.
• If the unit is left in a car parked in the sun, be sure to choose a location in the car where the unit will not be subjected to the direct rays of the sun.
• Use the unit within a temperature range of 0^ to 40^ (32°F to 104°F). If it is used in temperatures outside this range, an irregular display (i.e., 88.88...) may appear. If it is used in temperatures lower than this range, the display may change very slowly. These irregularities will disappear and there will be no damage to the unit when the unit is used in its recommended temperature range.
• In vehicles or buildings, radio-reception may be difficult or noisy. Try listening near a window.
• Reception of around 3.64 MHz may be difficult because of internal spurious signals generated by the built-in oscillators.

On safety

• The unit is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the unit itself has been turned off.
• Disconnect the AC power adaptor from the wall outlet when the unit is not to be used for a long period of time.
• The name plate indicating operating voltage, etc., is located at the rear of the unit.
• Should any solid object or liquid fall into the unit, unplug the unit, and have it checked by qualified personnel before operating it any further. Make sure that no liquid or foreign material enters the DC IN 3V jack of the unit. This may lead to the malfunction of the unit.
• When the casing becomes soiled, clean it with a soft dry cloth dampened with mild detergent solution. Never use abrasive cleansers or chemical solvents, as they may mar the casing.
• Since a strong magnet is used for the speaker, keep personal credit cards using magnetic coding or spring-wound watches away from the unit to prevent them from possible damage caused by the magnet.
• When there is lightning and you are using an external antenna, immediately disconnect the AC power adaptor (if connected) from the wall outlet. Never touch the antenna wire when there is a lightning storm.
• Never connect a ground wire to a gas pipe

Tips on radio waves

What is SSB (Single Side Band)?

SSB is very popular among ham and business radio transmissions, and is commonly used in many amateur bands because of its superiority in signal intelligibility. Its impressive signal intelligibility is achieved with minimum interferences when compared to DSB (Double Side Band) owing to its half bandwidth structure.

In general, SSB transmissions employ the USB (Upper Side Band) modulation, while amateur band transmissions below 10 MHz employ the LSB (Lower Side Band) modulation.

Conventional radios without a BFO (Beat Frequency Oscillator) circuit cannot receive SSB transmissions successfully. This unit can receive SSB transmissions successfully with the built-in BFO (Beat Frequency Oscillator) circuit.

What is CW (Continuous Wave)?

CW is also popular among ham and business radio transmissions. Unlike other signals, the amplitude of a carrier is not modulated for CW transmissions. CW transmissions convey information by interrupting the carrier and use Morse code as a means of communication.

This unit can receive CW transmissions successfully with the built-in BFO (Beat Frequency Oscillator) circuit as beat sound only. To fully comprehend the information transmitted by CW transmissions, an understanding of the Morse code is prerequisite.

What is synchronous detection?

There are two underlying obstacles in optimum AM reception: distortions due to fading and interferences from adjacent broadcast stations.

The synchronous detection is effective in solving these obstacles.

Distortions due to fading are generally caused by over-modulation which occurs when a carrier component of the received signal is attenuated along the way. The synchronous detection circuit of this unit generates a pure carrier frequency with no level variation which is ideally synchronized with the original carrier to compensate for the attenuated carrier component, thus dramatically reducing distortion.

Likewise, AM (LW, MW, and SW) broadcast generally employs DSB (Double Side Band) signals for transmissions in which the modulated signals are transmitted using both the upper and lower side bands (USB and LSB). In most cases, one of the side bands is affected by interferences from adjacent broadcast stations (i.e., beats). The synchronous detection circuit of this unit extracts one of the two sides (USB or LSB) of the DSB (Double Side Band) signal which is free from interferences. This allows clear reception without the interferences from adjacent broadcast stations.

This side is received only.
