HP105/HP405 User manualPage. 11Basic OperationsThis section describes how the standard operations work. Standard operation can be changed byprogramming, moreover the functions the radio includes can be modified via an IBM compatible PC. Forthis reason the way your radio operates may be upgraded and may slightly differ from what is describedhere.! IMPORTANT: Due to the full programmability of the radio, certain commands could beunavailable. In case of doubts please contact your dealer/radio network administrator for furtherdetails.Switching the radio ON/OFFTo switch the radio on:1) Rotate the PWR/VOL knob clockwise until the radio is switched on: the CPU will start an autotestshowing in sequence:• LED will light GREEN, then RED and finally OFF.• A beep confirms that the autotest is passed! The self-test goes very fast, therefore the LED could not be seen.To switch the radio off just rotate the PWR/VOL knob anticlockwise.Adjusting volumeThe PWR/VOL knob is used to adjust the RX volume: just turn it clockwise to increase or anticlockwise toreduce it.Channel selectionIf your radio has been programmed with more than one channel you can easily change it. To select achannel, turn the channel selector knob clockwise or anticlockwise until the channel indicator on the knobmatches the wished channel.ReceptionYour radio could be previously programmed to work, channel by channel, in “Open traffic” or “GROUPMODE (CTCSS/DCS)”. Please have a look to each description and ask your radio network manager ordealer which mode your radio channels work.• OPEN TRAFFIC: in this case you will hear any communication which will be transmitted on theselected channel. When the right carrier is received your squelch will unmute, you will see the statusLED glowing green and you will hear the message.• GROUP MODE:• CTCSS/DCS (Continuous Tone Code Squelch System - Digital Coded Squelch): they are systemswhich use particular TX signalling (a continuous sub audio tone for CTCSS or a digital code forDCS) as an access “key” to work a repeater (encoder) or to unlock the party’s signalling sensitivesquelch. This last condition allows to share more radio networks in the same frequency. In thiscase you will receive only messages coming from parties sending a proper TX signalling. DuringCTCSS/DCS operation the radio may be set-up so that the appropriate CTCSS/DCS decoder
HP105/HP405 User manualPage. 12enables the speaker. Speaker will remain muted until the correct CTCSS tone or the correct DCScode is received. In case of unmuted speaker, the message will be heard and the status LED willglow amber. Units of the same group are not affected by communication on the same channel withwrong CTCSS/DCS." CTCSS/DCS allows to share more than one radio network in the same frequency, however theyare just useful to avoid disturbing stations not owning of the same network with messages notrelated to them. In any case, if more than one station is transmitting at the same time, this willcause an interference. Don’t transmit if the status LED is glowing. Wait till nobody istransmitting on the channel.MonitorMonitor button can enable / disable “GROUP MODE (CTCSS/DCS)”.1) To enable GROP MODE. Press MON button. A Sub Audible Tone mutes your speaker.2) To Disable GROUP MODE. Press MON button. You are working in “Open Traffic”.! NOTE: if CTCSS/DCS tone is not programmed, GROUP MODE function is not available.3) Press and Hold MON button: internal squelch is disabled and your speaker in unmuted. Everyenvironmental noise is heard.TransmissionWhen you need to transmit please get used to follow all these steps:1) Ensure that the channel is not busy (otherwise you will create an interference, please wait till thatcondition).2) Press the PTT key: the status LED will glow red.3) Start talking at a normal voice level at approximately 10 cm from the microphone (keep the PTT keypressed).4) When your message is over, release the PTT! Don’t shout! It won’t increase the distance range, but rather will make you heard distorted.! Don’t release the PTT before your message is over or start talking before pressing it, otherwiseyour message will be “chopped”.! A handheld radio doesn’t normally allow to talk and receive simultaneously, for this reason makeyour messages with a reasonable time. When you are talking the other parties can’t do that, sodon’t occupy too much the channel. Use the common sense.! The radio might be programmed with a timeout timer which automatically put your radio inreception if you talk too much (after a preset time). In this case release the PTT and wait for fewseconds: the radio TX features will be automatically restored. Ask the network responsible or yourdealer for further details.! The radio might be programmed with a busy channel lock out which automatically disablestransmission if your channel is busy.
HP105/HP405 User manualPage. 13Transmission PowerYour HP105/HP405 can transmit with two power levels according to the distance of your party station(s).This option is programmed via PC and it can not modified by the user. We do recommend, when possible,to use the Low power: it will increase the battery duty and will reduce the risk to make interference withstations not owning to your radio network which may sharing the same channel with you.! If the low battery mark is "blinking" (Low Battery indication), the Unit will then automatically revertto Low RF Power when transmitting in order to help prolong the Battery's operational life. In thiscase, two short beeps will be heard before transmission.Scanning channelsIf you have more than one channel programmed, your HP105/HP405 can scan them: in other words it cancycle through them and stop when a signal is detected.The advanced scan functions of the radio allow to optionally look for carrier or carrier with CTCSS/DCS orCTCSS.1) To activate the scan Switch Off and then Switch ON the radio holding MON and FUNC buttons.2) A long beep will be heard when enter the SCAN MODE.3) During scanning the LED will blink amber.4) Only the channel in the Scan List will be monitored for activity. The Scan List is programmed via PC.5) During scanning the channel selector knob becomes invalid.6) To stop channel scan Switch Off and then Switch ON the radio holding MON and FUNC buttons.7) One among the programmed channels can be assigned as Priority Channel. The scanning will lookback at the priority channel with high frequency.8) User can select the priority channel:9) To select Priority channel, before starting the Scan Mode (before switching On the radio) select thechannel using the selector knob.! NOTE: If the Scan List has no channels, a low tone (error beep) will be heard when you switchOn the radio holding MON +FUNC and radio will not start the Scan Mode. At least two channelsmust be in the Scan List for the Unit to be put in the SCAN Mode.! When a proper signal is received on a channel, the radio will stop scanning and audio willbecome audible. When the activity on that channel ceases, the unit will automatically resumescanning.! If CTCSS/DCS have been previously programmed, the scanning will stop only if the receivedcarrier has the appropriate signalling.! If PTT is pressed during scanning, the radio will transmit on the first vacant channel. In case of noactivity, the Unit will automatically resume scanning.Advanced OperationsIn this section we’ll describe some advanced operation which you can do with your handheld transceiver:
HP105/HP405 User manualPage. 14Handsfree transmission (VOX)VOX (Voice Operated eXchange) is an automatic system which allows you to automatically switch thetransmission in hands free mode just by speaking in the built-in microphone of an headset (not providedwith the unit). Please ensure that the handset is suitable for your transceiver as reported in the paragraph“Microphone connection”. To insert the VOX and adjust sensitivity:1) Switch on the radio keeping pressed the FUNC key.2) Connect the optional headset with built-in microphone to the microphone connector located on thetransceiver’s side.10) Ensure that the headset’s built-in microphone is located close to the side of your mouth.11) Hold the FUNC key for more than 2 seconds to toggle VOX sensitivity from HIGH to LOW and viceversa. Adjust the VOX sensitivity in order to ensure a stable transmission when speaking with a normalvoice level." We recommend to set the just minimum sensitivity as possible. A too high value could causeaccidental transmissions, especially in hi-noise environments.! PTT button is disabled during VOX.
HP105/HP405 User manualPage. 15Care and MaintenanceBattery PacksInformation on rechargeable batteries• When the battery pack is new it doesn’t provide 100% of its efficiency; it means that it might bedischarged earlier. To reach the full battery life you have to “run-in” the battery with at least 3-4deep charging/discharging cycles, after that it will reach its maximum capacity. Please see“Properly charge of battery packs” for further details.• Should you properly use the battery pack, you will obtain at least 400 charging/discharging cycles(300 with the optional rapid charger). The battery duty will progressively reduce after 2/3 of its life(approx.).• Rechargeable battery packs lose their charge with the time if left unused (self discharge); this isnormal. A NiMH (Nickel Metal Hydrate) battery can reduce 10 to 20% of its stored energy in fewdays.Properly charge of battery packs1) Ensure that the radio is switched off,.2) Insert the radio into the cradle as explained in the paragraph “Charging the battery pack”3) Wait the necessary time to provide a full charge. If the pack isn’t completely discharged you will needless than 8 hours." Don’t overcharge the battery: always remember to remove the radio after the necessary time." The battery charger is for indoor use only.! When possible, charge the battery when it is fully discharged or, at least, you have used it for themajor part of its duty; otherwise the battery’s duty could be temporarily reduced. Please see theparagraph “Memory effect”.! Don’t remove the radio before the necessary time, otherwise the battery’s duty could betemporarily reduced. Please see the paragraph “Memory effect”.Memory effectThe supplied NiMH (Nickel Metal Hydrate) battery pack is made with a more advanced technology thannormal NiCd (Nickel Cadmium) battery. For this reason it is virtually free of what is called “memory effect”,which affects NiCd batteries. Memory effect is a temporary capacity reduction which reduces the batteryduty. Memory effect may occur just if you regularly charge the battery when you haven’t discharged it atleast at 50-70%. Memory effect can be easily avoided by following these simple rules:
HP105/HP405 User manualPage. 16• When possible charge battery packs only when they are completely discharged, i.e. when thebattery icon has no bars inside.• Don’t remove the battery from the charger before the necessary time to provide a full charge.• Provide at least two deep charge/discharge cycles per month.• The best way to avoid memory effect is to use two battery packs and alternate their use with theradio. This will allow you to keep on your transceiver’s operation by replacing the battery pack justwhen it’s fully discharged and use the spare (charged) one. At the end of your working day you willcharge the discharged pack for 8 hours.Erasing memory effectMemory effect can be easily erased just by applying 3-4 deeper charge/discharge cycles:1) Use the battery fitted in the radio and wait till the radio switches off.2) Wait at least one hour and then try to switch on the radio: you will note that some energy has restoredin the battery, because the radio can be switched on.3) Leave the radio in RX until the radio switches off again.4) Repeat steps 2) and 3) three times.5) Fully charge the battery for 9 hours and check the battery duty. If some memory effect still exist goback to step 1.! If the battery duty doesn’t improve after three of the over stated cycles, it means that your batterypack is faulty or has reached the end of life (please see “Information on rechargeable batteries”).In this case please ask your dealer to provide a new battery pack.Warnings for battery and chargers usePlease use these cautions to avoid damaging battery packs or the transceiver:" Before using the battery charger carefully read any related warning or caution." Don’t short battery terminals: this may cause fire, burns or explosions." Never dispose batteries into fire they may explode causing fire, burns or explosions.
