The CPU performs arithmetic processing while taking in required external data from the input port or transmitting and receiving data to and from the RAM according to this program, and outputs processed data from the output port as necessary.

In FIG. 4, reference numeral 20 denotes a portable radio communication device.
And a transmitting / receiving antenna 13 as shown in the figure, and a PTT switch 17 on the side of the wireless communication device.
The PTT switch 17 has a structure that can be operated with one hand so that the portable wireless communication device 20 can be easily operated by hand. 16
Is a power switch.

The portable radio communication device 20 configured as above is
In general, as described in the conventional example, the transmission mode setting at the time of transmission includes a "normal mode" and a "lock mode". In the "normal mode", the portable mode is set only when the PTT switch 17 is continuously pressed. The wireless communication device 20 is set to the transmission state (the transmission means 5a while the PTT is pressed in FIG. 1), and the PTT switch 17 is set.
When the pressing operation is released and the PTT switch 17 is released, the receiving state is set (the receiving means 5b for PTT releasing). on the other hand,
In the "lock mode", every time the PTT switch 17 is pressed, the transmission state and the reception state are set alternately to lock the mode (the transmission means of the PTT pressing and the receiving means 6 of the PTT re-pressing).

Now, one P provided in the portable radio communication device 20
An operation function for setting the "normal mode" and the "lock mode" by operating the TT switch 17 will be described with reference to the flowchart of FIG.

In order to set the portable wireless communication device 20 to the “normal mode” or the “lock mode”, the PTT switch 17
When the power switch 16 is turned ON while pressing (step S1), the microcomputer 18 detects that the power switch 16 has been turned ON, and at the same time determines whether the PTT switch 21 of the transmission switch is pressed. Judge (step S2).

When the power switch 16 is turned on while the PTT switch 21 is being pressed (the power-on operation means 1 while the PTT is being pressed), the portable radio communication device 20 is set to the "normal mode" or the "lock mode". (The normal mode or the lock mode setting means 4), and the portable wireless communication device 20 performs the mode switching process so as to perform the switching operation from the mode when the power switch 16 is turned off to another new mode. Is performed (step S3).

For example, if the portable wireless communication device 20 operated by the above-mentioned operation procedure is set to the "normal mode" when the user wants to set the "lock mode", the power switch 16 is turned off again. As described above, by turning on the power switch 16 while pressing the PTT switch 21,
The portable wireless communication device 20 stores the “normal mode” of the previous setting state immediately before the power switch 16 is turned off, and can set the “lock mode” by the current operation setting. The setting for switching from the “lock mode” to the “normal mode” can be processed by the same operation.

As described above, when the power switch 16 is turned on while the PTT switch 21 is being pressed, the "normal mode" and the "lock mode" are alternately set, so that the user can set any desired mode setting. It can be done easily.

When the power switch 16 is turned on, the PTT switch
If the power switch 17 has not been pressed (the power-on operation means 2 for pressing and releasing the PTT), the microcomputer 18 detects only the ON operation of the power switch 16 (step S2), and the microcomputer 18 detects the ON operation of the power switch 16 and the previous setting when the power switch 16 was turned OFF Then, the storage mode is set to the “normal mode” or the “lock mode” (previous storage mode setting means 3 and step S4).

For example, when the power switch 16 is turned OFF in the previous "lock mode", the microcomputer 18 stores the "lock mode" as a storage mode, and when only the power switch 16 is newly turned ON, the microcomputer 18 18 calls the "lock mode" and sets the portable wireless communication device 20 to the "lock mode" (normal mode or lock mode setting means 4).

As described above, when the portable wireless communication device 20 is used,
When turning on the power switch 16, the user decides whether to use the portable wireless communication device 20 in the "normal mode" or "lock mode", and turns on the power switch 16 while pressing the PTT switch 17. Or ON only the power switch 16
It is easy to select whether to operate or to set the desired mode.

That is, since the mode setting can be easily performed, for example, when the portable radio communication device 20 is set to the “lock mode” and is operated while being locked in the reception state, the PTT switch 17 is operated due to some erroneous operation. Is pressed again, and the portable wireless communication device 20 enters a transmission state and is left unattended for a long time. In order to prevent problems such as overheating for a long time,
A time-out timer (TOT) function is provided, and the transmission state is automatically switched to the reception state at a predetermined time by the TOT, and the above-mentioned safety measures for preventing power consumption and heat generation may be added. It is possible.

[Effects of the Invention] As described above, the mode setting of the wireless communication device according to the present invention, particularly the portable wireless communication device 20, is performed by using one PTT.
By operating the switch 17 together with the power switch 16, the "normal mode" or "lock mode" of transmission switching can be arbitrarily selected and used, the operation is simple, and the function used can be improved. effective.

In particular, the “lock mode” of the transmission switching is an effective function in a situation where the PTT switch 17 cannot be continuously pressed and operated in the operation of the portable radio communication device 20. Lock mode "with wireless communication device 40
The merit that can be set has a great effect.

The "lock mode" is transmitted while receiving. For example, when it is not necessary to frequently switch transmissions as in duplex communication, the "lock mode" is set so that the troublesome operation of the PTT switch 17 is eliminated. There is also an effect.

In addition, the initial setting function of the transmission switching mode largely depends on the software of the built-in microcomputer 18, which has the effect that the functions can be increased without increasing the cost, and the implementation is easy. It has excellent features.
