1. AAA ALKALINE HOBBICO HCAP0340 LED ON OFF SWITCH FREQUENCY CHECKER T2unz LEDS Each of the 50 channels in the 72MHz band is represented on the Frequency Checker by its own dedicated red LED The Frequency Checker scans all frequencies in the band one by one This device does NOT scan all frequencies instantaneously When the power switch is turned on the Checker begins the scan starting at channel 11 72 010MHz as indicated by a brief flash of the LED marked 11 then steps to channel 12 72 030MHz etc until it reaches channel 60 72 990MHz after which time it will start over again at channel 11 It takes approximately 15 seconds for the Frequency Checker to scan through all 50 frequencies The Checker will continue this scanning process until the power switch is turned off When the Frequency Checker identifies that a frequency is in use the LED for that particular channel will stay on This means it is not safe to use that respective channel The Checker will then continue to scan the next channels in order and if a signal is detected on another channel its LED will stay on solid as well For example it is possible that all 50 LEDs could stay on if a signal is detected on all 50 channels although such a circumstance is highly unlikely Each LED will stay on until the Checker scans through all other remaining channels and back again at w

3. Hobsico LN 72MHz INSTRUCTIONS INTRODUCTION Hobbico s Frequency Checker is designed to scan all fifty R C frequencies in the 72MHz band and identify when another transmitter is operating on any such channel It s important to note that the Frequency Checker is NOT well suited to show very brief intermittent Rf signals that could cause interference which may be present in the environment near or between R C channels SPECIFICATIONS Input voltage 4 5V DC Operational current 20 1830mA Frequency identifiers 50 individual red LEDs Scan frequency 15 seconds Max operational temp Dimensions Weight 32 104 F 0 40 C 3 14 x 94 x2 36 80x24x60mm 2 05 oz 58g SPECIAL FEATURES Each frequency is identified by its own dedicated LED No programming or adjustments for ease of use automatically scans all frequencies when power is applied Requires 3 AAA alkaline cells not included Range is up to 300 feet w o external antenna Range is up to 1000 feet with external antenna available separately HCAP0341 Small and lightweight easily fits in a pocket or flight box IMPORTANT PRECAUTIONS Do not fly on a frequency that is already in use Failure to obey this warning can and likely will result in crashed models Always test your radio system before use by performing a complete range check to make sure there is a solid Rf link between the transmitter and receiver Refer to your radio s instructio
4. hich time the scan will start over If during the next scan of that channel the signal disappears the LED will turn off For reference see the list below to match the channel number to its respective frequency in the 72MHz band External Antenna Available Separately fS TTELEELLE Antenna Jack The 72MHz Frequency Checker has a built in antenna which is designed to receive transmitter signals from within a 300 foot radius If a greater range is desired an external antenna is available separately HCAP0341 Contact your local hobby shop for details Using the external antenna can extend the Frequency Checker s range to a radius of 1000 feet It s best to point the antenna skyward for best reception When using the external antenna extra channels might appear to be in use if the checker is physically located very near a Tx which is emitting a signal Moving the checker several feet away from the Tx should clear the problem If used inside buildings which have a lot of steel metal in the structure extra channels might inadvertently be shown and NOT using the external antenna may deliver the best results in this situation INDOOR FLYING SITES When used inside enclosed buildings particularly those constructed with a steel structure and covered with a metallic surface it s possible that the Frequency Checker might show some erratic behavior Such facilities can cause excessive reflection of Rf signa

6. n manual for further details Do not allow fuel or oil to make contact with the Frequency Checker s plastic case as it could result in damage to the case or the artwork Do not store the frequency checker in extreme heat exceeding 104 F or cold below 14 F in direct sunlight in high humidity in high vibration environments or in dusty areas Do not point a Tx antenna directly at the Frequency Checker This will make it more difficult for the checker to detect the signal being emitted from the Tx For best reception do not lay the Frequency Checker on the ground during operation Resting the checker on an elevated surface such as a table or flight box is recommended INSTALLING BATTERIES The 72MHz Frequency Checker requires 3 AAA sized alkaline batteries Looking at the rear of the Frequency Checker press the tab on the battery door then gently remove the door Pay close attention to insert the cells in the proper direction as shown here Re install the door after all batteries are installed If the condition of the batteries is in doubt install fresh batteries for optimum performance before use OPERATION ON OFF SWITCH The input power switch is located along the right side of the Frequency Checker Slide the switch to the upper position to turn the unit on Move the switch to the lower position to turn the unit off Make sure to turn the power switch off when not in use to prevent draining the batteries
