PowerCom Plus, PowerCom, and LiteCom all offer reliable, efficient communication between two or more people in noisy environments. Although these products are very user-friendly, please take the time to read this instruction manual carefully to ensure proper set-up and use of all features • PowerCom Plus and PowerCom are 2-way radio headsets pre-programmed to 22 or 14 channels in the FRS and/or GMRS frequency band with 38 privacy sub-channels. These units have up to 0.15 watts of transmitting power with a range of 2 km outdoors. The range will vary depending on local surrounding environmental conditions. • LiteCom is a 2-way radio headset pre-programmed to 5 channels in the 49 MHz frequency band. This unit has up to 0.1 watts of transmitting power with a range of 100M outdoors. The range will vary depending on local surrounding environmental conditions. • The PowerCom Plus/PowerCom headsets will not communicate with the LiteCom headsets. However, PowerCom Plus headsets will communicate with PowerCom headsets. • All models feature advanced ghost voice confirmations of mode and level selections. As an added bonus, the ghost voices are selectable by the user in every model. Language options are English, French or Spanish. Depending on the product purchased, they will communicate with other similar license-free radio products in the FRS, GMRS and 49 MHz frequencies. These devises comply with part 15 of the FCC rules and regulations. Operation of these devices are subject to the following two conditions: 1) These devises may not cause harmful interference, and 2) These devises must accept any interference received, including interference that may cause undesired operation Headset basics.... Refer to figure H. 1. (MT53H7A****) Wide padded headband – for over-the-head use (MT53H7B****) Neckband - for use under a hardhat (MT53H7P3E****) Slotted hardhat mount – snaps into slots of hardhats 2. Stainless steel headband wires – special bending processes ensure an even distribution of pressure around the ears. 3. Guide arms – slide assembly for easy height adjustment. 4. Ear seals – foam with liquid bladder for all day comfort, built-in pressure-relief canals ensure low pressure and effective sealing. See page 12 for replacements. 5. Antenna – flexible with fixed mount design and high reception quality 6. Audio jack - for external audio accessories including 2-way radios, cell phones, personal entertainment devises, see page 13 7. Battery cover – requires 2 standard 1.5-volt AA alkaline batteries, optional rechargeable battery pack available, see page 12 8. Key pad - for easy changing of modes, settings and levels. 9. Lip microphone – quick positioning metal boom assembly with an electret noise canceling condenser, see page 12 for replacements. 10. Cup microphones – amplify and reproduce in stereo inside the headset ambient noises and voices allowing the user to be fully aware of surrounding environment. (Only available with PowerCom Plus models). See page 12 for foam replacements. 11. Headset Push-To-Talk (PTT) – will key up lip microphone and activate the radio inside headset to start transmitting. 6 1 2 3 4 5 7 11 10 (H) 9 8 Getting Started... BATTERIES Open the battery cover (#7, Fig. H) and place two 1.5 Volt AA size batteries inside the compartment. Ensure that the + and – poles of the batteries are in the correct positions (refer to figure inside the battery cover). The headset is polarity protected in the event batteries are incorrectly inserted. When the batteries get low in power, a voice message saying “low battery” will be heard inside the headset. This message will be repeated in 2 minute intervals until the batteries are completely depleted, at which point the headset will have a voice confirmation saying “battery empty” and will shut off. Note(s): 1) Battery life span/operating time varies greatly depending on the type of batteries and how the headset is used. For example, with an alkaline battery with at least 2000 mAh, the operating time in low-power mode is about 30 hours at 10 % transmission, 10 % reception and 80 % stand-by. In high-power mode, the operating time under the same conditions decreases by about 10 %. At 20 % transmission, 20 % reception and 60% stand-by, the operating time is about 20 hours. 2) The headset has an automatic shut-off feature to save on batteries. It will turn itself off automatically after 2 hours if one of the following keys is not activated in that timeframe: (0) (+) (-) (PTT/VOX). A triple tone signal will be emitted every 30 seconds for 5 minutes prior to final shut down. ADJUSTING THE CUPS FOR FIT (Fig. J) 1. The cup guide arms (#3, fig H) slide up and down the metal wires. 2. For headband and neckband models, place the headset on your head, with one hand, hold the band (#1, fig H) in place and with the other slowly move the cup up/down the wire arms until they are in the comfortable and snug fit position. 3. For harthat mount position (fig. K) snap the headset helmet attachment into the slot of the helmet. Place the hardhat with headsets in place on your head and refer to 2. above for cup placement instructions. Th…

FCC ID: NUVMT53H74. P522/P526, Carsons rule calculation. 040218/mah Definitions. Bn = Necessary bandwidth M = Maximum modulation frequency D = Peak deviation For FRS Channels (Default) M = 2.55 KHz D = 2.5 KHz K = 1 Bn = 2(2.55) + 2(2.5) = 10.1 KHz For GMRS and BRS Channels (Reprogramming needed) M = 3 KHz D = 5 KHz K = 1 Bn = 2(3) + 2(5) = 16 KHz FCC ID: NUVMT53H74. P522/P526 Transmitter Modulation frequency response. 040218/mah The Peltor Headset MT53H7A4610, (FCC ID: NUVMT53H74), is built around a dedicated FRS base- band and PLL IC from CML, the CMX838. This IC contains highly stable digital filters for the transmit chain and also the limiter. The data for the transmit filters are illustrated in Fig 11 of the CMC838 data attached to this document as page 2. The graph marked narrow band is used as default. The graph marked wide band is used if the Transceiver is reprogrammed for the specific GMRS or BRS channels where 5KHz deviation is permitted.
