RP-300A,RP-300D
Outline
- There are two kinds with the electric wave translator of the electric wave of the transmitter for hearing. There are what receives 399Mhz band and is oscillated by 320Mhzes (RP-300A), and a thing which receives 320Mhz band and oscillates 399Mhzes (RP-300D). Reception is changed by three kinds (ABC, DEF), and all two kinds of oscillations are changed by the switch in two kinds (DF, AB), respectively. That is, many sets can be connected and it can use.
- The receiving part and the dispatch part will be become independent, respectively. a receiving part -- KUR-400 -- the same two dry cells of U5 are used Even if it puts in the power supply switch, the electric wave is not always sending. Only when the receiver of a translator receives an electric wave, dispatch of the electric wave for relay is begun for the first time. And since it waits and receives and it sometimes operates intermittently (2 seconds interval), the consumption current of a receiving part drops to 1/7 of continuation operation standby. It corresponds also to the sound starting transmitter. Even if an electric wave once stops, a receiving part does not shift to intermittent operation for 10 seconds. It will have a battery life by continuation use about 3 days. If the adapter (AD-RT3) of dry cell U3 is used, it will have ten days. a dispatch part the dry cell of U2 is used four days. A battery life will have a life on the 5 days in the state of continuation operation. If it is the transmitter of a sound starting system, it will have a battery also in ten days or in 20 days more. Also in the state of ON of the switch of a receiver, a transmitter sends a relay electric wave only after a receiver receives an electric wave. Only when there is a received electric wave, a relay electric wave is sent.
- The power supply of a dispatch part operates to stability until battery voltage becomes 3v, since the power supply voltage step up stabilization circuit is built in. Moreover, since the alarm circuit is built in if voltage becomes below stable operation, an alarm lamp lights up. In addition, when the power supply of a receiving part is turned on, an alarm lamp lights up momentarily. It is visible to the crevice between a volume knob and an antenna terminal. Immediately, when a battery is new, it requires time and becomes dark until it will go out, if it becomes old, although lighting goes out. A dispatch part is turned on first which sends an electric wave similarly. Please exchange batteries, if an electric light will be in a lighting state.
- Relay possible distance is about 1500m on the flat ground without an obstacle
- KUR-400DEF is used to receive RP-300A. KUR-400ABC is used for receiving RP-300D.
- Since many sets are connected and it can act as intermediary, many km beyond can also be relayed.
- Since the small transmitter of outputs, such as( KPV-300) or (CDV-500), and the transmitter for a telephone are receivable in the about 1km away place, it is very convenient.
- If the transmitter for a telephone or the transmitter of sound starting are relayed, prolonged automatic recording will be made using (KKCR-360).
Directions
- The battery is built in. Operation is set up before putting in the power supply switch of the place of a receiving part. A dispatch part pries and vacates the hollow of the end of a lid by attached metallic ornaments. RP-300A receives A, B, or C and sends the electric wave of D or F. RP-300D receives the electric wave of D, E, or F, and sends the electric wave of A or B. A change of a dispatch electric wave is visible to the inside near the antenna where the lid of a dispatch part is opened. The case of a receiving part performs a change of a received electric wave.
- A battery will be exchanged if a red alarm lamp will be in a lighting state. Two dry cells of U5 are put into a receiving part, and four are put into a transmitting part for the dry cell of U2. It is careful of direction to prevent mistakes. And a lid is closed as before.
- RCA terminal of an antenna is an object for reception. A screw terminal is an object for dispatch. The attainment distance of an electric wave is prolonged for a while by the straight line antenna from a helical antenna.
- If the power supply switch of a receiving part is put in, it will be in a state of operation.
- RP-300A is used to relay the transmitter of A, B, or C. The introduction reception setup is carried out. It sets to A, B, or C. D or F is sufficient as a dispatch setup. When you receive with a receiver, the receiver which can receive D or F is used (KUR-400DEF). Furthermore, one more set RP-300D is used to act as intermediary to a long distance more. A reception setup is set to D or F which set up the point. A dispatch setup is used as the channel surely different from the first transmitter. If it is A, it will surely be made B. An electric wave stops going out until both of the relay devices of a battery will be lost even if it starts a deadlock and the electric wave of the transmitter of the first A is lost if it is set as A.
- When you install, please be sure to carry out a check of operation. A situation changes considerably by the little difference in the place to install.
